Suggestion

I've noticed that the following will happen:

1. A PR is sent or updated
2. A review requests changes and the awaiting response label is added
3. The author addresses changes and re-requests review
4. Some time passes
5. Another review comes in

During 4. Some time passes, the awaiting response label is still on the PR - even though it's waiting for us to review it!

Proposal: let's add a repo automation that removes the awaiting response label from a PR when a review is requested on it? I think requesting a review generally implies a code response has been pushed.
