This change addresses the question in #6542 about using non-string
operators on string values by clarifying that Unleash SDK converts the
string values before performing the comparison.

Upgrading to 5.7 and above from earlier versions is a little
problematic. Let's document it.

## About the changes
When edge is configured to automatically generate tokens, it requires
the token to be present in all unleash instances.
It's behind a flag which enables us to turn it on on a case by case
scenario.
The risk of this implementation is that we'd be adding load to the
database in the middleware that evaluates tokens (which are present in
mostly all our API calls. We only query when the token is missing but
because the /client and /frontend endpoints which will be the affected
ones are high throughput, we want to be extra careful to avoid DDoSing
ourselves
## Alternatives:
One alternative would be that we merge the two endpoints into one.
Currently, Edge does the following:
If the token is not valid, it tries to create a token using a service
account token and /api/admin/create-token endpoint. Then it uses the
token generated (which is returned from the prior endpoint) to query
/api/frontend. What if we could call /api/frontend with the same service
account we use to create the token? It may sound risky but if the same
application holding the service account token with permission to create
a token, can call /api/frontend via the generated token, shouldn't it be
able to call the endpoint directly?
The purpose of the token is authentication and authorization. With the
two tokens we are authenticating the same app with 2 different
authorization scopes, but because it's the same app we are
authenticating, can't we just use one token and assume that the app has
both scopes?
If the service account already has permissions to create a token and
then use that token for further actions, allowing it to directly call
/api/frontend does not necessarily introduce new security risks. The
only risk is allowing the app to generate new tokens. Which leads to the
third alternative: should we just remove this option from edge?

A v1 Java tutorial for docs! I used Java SDK to log flag statuses when
the Java app is running and connected to Unleash.

It's fairly simple and open to feedback for a new iteration to improve
the intro tutorial. I do weekly documentation improvement PRs!
I've held an internal knowledge sharing session on this already. If
someone can think of a better phrasing for the background, I'm all ears.
I think it's just nice to have this documented, so people remember that
our logging framework already has a good way to format errors when you
use the API `logger.error("<message>", e)`
Fixes ##5799 and #5785
When you do not provide a token we should resolve to the "default"
environment to maintain backward compatibility. If you actually provide
a token we should prefer that and even block the request if it is not
valid.
An interesting fact is that "default" environment is not available on a
fresh installation of Unleash. This means that you need to provide a
token to actually get access to toggle configurations.

Having old ADRs makes it harder for newcomers, that have to navigate
through many ADRs and spot the ones that were superseded by others. We
can save the mental burden by just moving the old ones to a deprecated
folder
This change updates the change request scheduling docs to include
information about what happens when a strategy or segment is updated
in the background, as well as updated information about the emails
that it sends out.
This PR updates the images in the feature flags best practices guide to
work on dark backgrounds by giving them white backgrounds (making them
non-transparent).
In doing so, it replaces the links to GitHub with docusaurus assets
(which also yields faster loading) and uses captions to describe the
images.
So we have a place in the docs to refer users struggling with getting
metrics from Edge after upgrade to Unleash v5.9.0, this PR adds a small
troubleshooting note about two fixes.
1. Upgrade Edge
2. Use environmental flag to re-enable old endpoint

A new Python Examples doc:
- underneath Python tutorials
- explores more use cases for Python with feature flags in Unleash,
building on top of our existing Python tutorial.
- This was edited and reviewed by team members via [Google
Docs](https://docs.google.com/document/d/1gO5KSShCKObbdjP-TobIjaOLqTP5_V1YcTLXAp5DA2g/edit#heading=h.oblpm3ljyzs8)
before adding to our docs site.

- Reducing the amount of steps to implement the Python app feature flag
- fixed spaces & indentations in Python code snippets (mentioned in past
PR review)
- `git clone` my forked repo so we can customize that code in the future
as we improve it, without being blocked.

More improvements to be made to the HTTP calls in `routes.py` as I
continue working on resolving some issues I'm running into in the app.

## Key Updates in the ADR
- **Separation of Migrations in PRs**: Migrations are now required to be
carried out in separate pull requests. This change is intended to
improve the monitoring and management of database schema changes during
deployment.
- **Primary Key Requirement for New Tables**: A new paragraph mandates
the inclusion of primary keys in all new tables, emphasizing the
importance of data integrity, efficient data retrieval, and supporting
table relationships. Additionally, by adding primary keys, we resolve
the issue of migrations failing during upgrades in replicated database
setups, as we are not using PostgreSQL replica identities. Exceptions to
this rule require a compelling justification.
Also added better structuring and styling to ADR for better readability.

Let's update our tutorial titles in the left navigation menu so it's
shorter and simpler.
This will _not_ change the metadata and doc titles when you click on
them. Only the label in the nav.

A new tutorial to get developers to implement feature flags into a
Python Flask app.
We have steps that guide them through the process using a simple
full-stack survey app.
Based off of a reviewed [Google Doc
here](https://docs.google.com/document/d/1YlG-TyQcMEyUrMjiWlYrd-J5DXog5ErbvSKAyuzKAnU/edit#heading=h.ryvmv14764i3)
The tutorial can go live in the docs nav in a new Python section, where
the Python examples will follow.

This is a large PR with all of the React examples building on top of the
original tutorial.
Based off of this Google Doc:
https://docs.google.com/document/d/1m3ujgyrkJTCGLsEsBr1_eq4HQKqsf-lfvGFDJobns44/edit
I also included updates to the React tutorial links so they are relative
paths, not full URL paths.
I propose we make fast-follow updates to this piece of documentation for
changes we need to make in order to release and iterate on minor
updates.

We want to deprecate and eventually remove the option for admin tokens.
This PR updates the docs to inform readers about the deprecation as well
as recommending what they can use instead.
This PR describes in closer detail what happens when the user who
scheduled a change request is deleted. It mentions the new suspended
state and what the user can do to get out of it.
This change adds a mention of frontend API tokens to the docs. We've
had this functionality for a while, but it appears not to have been
documented.
Realized this as part of triaging #3005.
This commit updates the change request docs to talk about how the new
scheduled state works.
The subsection is marked as "in development", saying that it can
change at any moment until the feature is released.

We've made some first round updates to the React tutorial:
- making it more SEO-friendly with ordered lists, sequential language,
description of the JS library
- Switched over the demo app to point to an open source project:
[Cypress Real World
App](https://github.com/cypress-io/cypress-realworld-app)
- included best practice considerations for client-side development
- updated URL path to point to `/feature-flag-tutorials/react` for
simplification

Would love feedback on if there's a need for more screenshots? Don't
want to be too screenshot-heavy though I imagine.
And need feedback on the descriptions of "Considerations for using
feature flags in react"
https://github.com/Unleash/unleash/compare/react-improvements?expand=1#diff-96d4956f49f80cd76489a72d4d88c2956ce9dcc695f66fe014ad1185e37cb589R21
Want to make sure that what I described makes sense or if it could use
some tweaking to convey the right message clearly.
