This PR disables the "create feature flag" button when you've reached
the limits.
This one is a little more complex than the other UI limits, because we
also have to take into account the project feature limit. I've tried to
touch as little as possible, but I _have_ extracted the calculation of
both limits into a single hook.
This PR disables the filtering capability in the front end for unknown
users.
Modifying the back end to support filtering for unknown users is not
something we want to do yet. It's possible, but it requires adding a lot
of special cases to the handling code (refer to [PR
#7359](https://github.com/Unleash/unleash/pull/7359)), which we'd like
to avoid if possible. To avoid annoying cases where the filtering
doesn't work as expected and breaks user expectations, we're disabling
the filtering capability for unknown users in the front end.
We can consider whether to enable back-end results for unknown in the future if we get
user feedback that it's important.
This PR works by changing the avatar cell component. When the user has
id 0 (and is therefore unknown), we:
- set aria-disabled to true. This alerts users with assistive tech that
the button is disabled, but it doesn't take it out of the tab order, so
it's not mysteriously missing.
- change the tooltip text, telling users that they can't filter by
unknown users.
- disable the avatar callback function, so clicking on the avatar
doesn't do anything.
The accompanying tests assert this functionality.
I considered also updating the screen reader text, but I think that
would add more confusion or be more information than the user needs.
According to MDN's article on the [aria-disabled
attribute](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-disabled):
> [the aria-disabled] declaration will inform people using assistive
technologies, such as screen readers, that such elements are not meant
to be editable or otherwise operable.
**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.

This PR lets you filter by flag creator by interacting with the user's
avatar.
Additionally, I've switched the custom popover for the standard tooltip
that we use elsewhere in the table. This gives the table a more cohesive
feel. As such, I have also deleted the component created in a previous
PR, because it's no longer in use anywhere.
It now looks like this (when tabbed to; notice the focus ring):

This PR changes the behavior of the project tables' environment columns
based on input from customers.
Up until now, you have been shown either the first project or the first
three projects in the list of the project's environment. The decision on
whether to show one or three is based on screen size. The breakpoint
appears to be about 1280px. Above that you get three, below it you get
one.
With this PR, we'll show you *all* environments by default, regardless
of screen size. However, that's just for the default values. If you
manually change column visibility, those changes will of course be
respected.
I've used a new package, `css-mediaquery`, to test that all screen sizes
show all envs.
