In #166783 I got into a state where a few tests were failing due to a (resolved) OOB failure:

I wanted to re-run them. However I could neither:

• Click "rerun all check-runs" (the button does not exist)
• Merge a PR to head, as I'd do on master (no commits have landed)

I could click a few times (waiting) for each failure, or push an empty/blank commit, which can't be done in the UI.

If we couldn't get a "rerun all check-runs" to work, it would be nice to expose a way to go to, something like:

https://flutter-dashboard.appspot.com/#/flutter/flutter-3.32-candidate.0/presubmit/166783

And be able to click a "re-run previously failing" button.
