Codelab update April '26 (#2386)

Main addition is converting the GenUI Intro codelab to use
`codelab_rebuild`

Note, there are issues with Flutter `beta` and `main` on macOS. I'm
hoping these issues will resolve naturally.

## Pre-launch Checklist

- [x] I read the [Effective Dart: Style] _recently_, and have followed
its advice.
- [x] I signed the [CLA].
- [x] I updated/added relevant documentation (doc comments with `///`).
- [x] All existing and new tests are passing.

If you need help, consider asking for advice on the #hackers-devrel
channel on [Discord].
