Rollup merge of #156171 - teor2345:missing-coro-test, r=cjgillot

Fix a coroutine UI test which is missing `#[coroutine]`

This looks like a typo, although the test now produces a different error to the other errors in the file.

I also fixed some comment typos in tests, happy to drop that commit if you don't want to review it.
