Add stitches and material-ui tests for new link behavior + fix TypeScript types when imported (#36474)
Adds additional tests for material-ui and stitches based on questions in the Twitter thread.

Fixes TypeScript types when `LinkProps` is imported and used in combination with `<button>`, added a TODO to change this at a later point when the new behavior is the default instead of opt-in.
