We're migrating to ESM, which will allow us to import the latest
versions of our dependencies.

Adds focus styles to the env accordion header only when the focus is on
the header itself (not on the env toggle inside the header). The focus
style is consistent with what we do for other accordions (dashboard,
milestones).
Middle one is focused:

Focus is on the toggle inside the top one (yeh, we should have better
focus styles for toggles; but that's not for now):

Open and focused:

Getting the consistent background for the header when it's open is a
little tricky because the accordion container and summary are split into
different files. ~~This first iteration used a class name for the
specific header (because envs can have multiple accordion headers inside
them, e.g. release plans) and setting a CSS variable in the summary, so
that the background matches.~~ I found out that I only need to set it in
the parent anyway 😄
Without it, you get this (notice that there is a little white outside
the lower corners):

Implements the drag-n-drop tooltip the first time the user sees a
strategy drag handle on the feature env overview. It uses React Joyride,
which is the same system we use for the demo.
The design is a little different from the sketches because I couldn't
find a quick way to move the content (and the arrow) to be shifted
correctly.
If the demo is also active the first time a user visits a strategy page,
it'll render both the demo steps and this, but this tooltip doesn't
prevent the user from finishing the tour. It might be possible to avoid
that through checking state in localstorage, but I'd like to get this
approved first.
The tooltip uses the auth splash system to decide whether to show the
tooltip, meaning it's stored per user in the DB. To avoid it
re-rendering before you refetch from the back end, we also use a
temporary variable to check whether the user has closed it.

If the tour is also active:

Implements the new strategy list design for default strategies. Moves
the old impl into a legacy file. Also: removes the description from the
strategy item. From my digging, we only showed this for default strategy
items and it didn't really provide any useful information. The only
other place you can add a description is for custom strategies (at least
that I could find), but these are deprecated and we never show the
description when you apply the strategy anyway.
Rendered:

Without the flag (nothing changes):

Moves strategy titles and names onto the same line, as per the new
designs.
In doing so, I've also updated the component to use a more semantic
hgroup with the header being the strategy title if it exists or the
strategy name if not.
The downside of being more semantically correct here is that we need to
know what header level we want the strategy to use. In most cases,
that's 3 (e.g. flag name > environment > strategy, release plan >
milestone > strategy), but for plans on flag envs, it's 4 (flag name >
env > milestone name > strategy).
I've also taken the opportunity to fix a little mistake I made earlier.
`ol`s can only have `li` children, and I'd forgotten to wrap a nested
`ol` inside an `li`. The changes in `EnvironmentAccordionBody` all
relate to that change. Because we now have several layers of lists
nested within each other, dealing with styling and padding gets a little
tricky, but CSS has the power do help us out here.
Rendered:

Updates the strategy list based on the new designs and moves the current
versions of the touched components into `Legacy...` files (the vast
majority of changes are that and updating imports). The relevant changes
to the components are listed in their original files.

## Next steps
There's two items to review for improving these current comments (also
noted inline):
- Whether to aria-hide the "or" separator or not (I need to read up a
bit and think whether it makes sense to show that or not)
- Changing the list of strategies into an actual ordered list (`ol`).
That'd reflect the semantics better.
Next would be checking the other places we use strategy lists and then
updating those too. In doing so, I might find that some things need to
be updated, but I'll handle those when I get there.
There's also handling release plans.
**Upgrade to React v18 for Unleash v6. Here's why I think it's a good
time to do it:**
- Command Bar project: We've begun work on the command bar project, and
there's a fantastic library we want to use. However, it requires React
v18 support.
- Straightforward Upgrade: I took a look at the upgrade guide
https://react.dev/blog/2022/03/08/react-18-upgrade-guide and it seems
fairly straightforward. In fact, I was able to get React v18 running
with minimal changes in just 10 minutes!
- Dropping IE Support: React v18 no longer supports Internet Explorer
(IE), which is no longer supported by Microsoft as of June 15, 2022.
Upgrading to v18 in v6 would be a good way to align with this change.

## About the changes
Refactoring the colors for the light theme to be much easier to continue
with dark mode
This is the first step to finish dark mode
https://linear.app/unleash/project/[low][s][alpha]-dark-mode-in-unleash-admin-ui-31b407d13c4b/1
This PR uses `main-theme` as a placeholder for `dark-theme` for now due
to the new changes. Still need to set the correct values here.
