Convert ComposerAlertMolecule to use alert levels.

[kaylendog]

Content

Introduces ComposerAlertLevel and modifies ComposerAlertMolecule to accept a level argument over isCritical. Displays an icon appropriate for the level if no avatar is specified.

Motivation and context

The designs for UX as part of element-hq/element-meta#2875 call for an alert using the info colour palette, which the current component doesn't support.

Tests

The ComposerAlertLevel.Critical is identical to previous iterations:

This was tested using the identity reset alert mechanism.

[github-actions]

Thank you for your contribution! Here are a few things to check in the PR to ensure it's reviewed as quickly as possible:

• Your branch should be based on origin/develop, at least when it was created.
• The title of the PR will be used for release notes, so it needs to describe the change visible to the user.
• The test pass locally running ./gradlew test.
• The code quality check suite pass locally running ./gradlew runQualityChecks.
• If you modified anything related to the UI, including previews, you'll have to run the Record screenshots GH action in your forked repo: that will generate compatible new screenshots. However, given Github Actions limitations, it will prevent the CI from running temporarily, until you upload a new commit after that one. To do so, just pull the latest changes and push an empty commit.

The code looks good, but it seems that for some reason (probably because you are using a fork) the screenshot cannot be recorded.
If the PR is ready to be merged (i.e. not a draft anymore), I can merge it in a branch of me and record the screenshot from there.

I suspect so; based on what I gleaned from the logs, my fork is missing a Maestro access token. This is ready, so I'll mark this as ready for review, and we can go from there!

I'm slightly worried the dark theme info alert doesn't have good contrast - I had similar grievances on element-hq/element-web#31156, which I believe is a question for the design team.

Thanks for the update. One final comment, then I'll merge your branch to mine to be able to record the screenshots.
