Add a github workflow for reverting PRs.#184593

This is a simple github workflow to replace the revert service in cocoon. It is set to use a tag called `revert_wf` for now, so that it doesn't conflict with the existing service. Once we have tested this workflow and are happy with it, we can turn down the cocoon service and change this workflow to respond to the `revert` label instead.

Is there a code injection vulnerability here if the $REASON from someones pr tries to escape its way out of the shell?

I believe expanding an environment variable inside double quotes is safe. Contents of the variable are automatically escaped properly. For example, you can't end the quote early, because if the comment contains a quote, bash replaces it with an escaped quote \".

This is just taking the information we've gathered and attaching it to the github environment so it can be accessed in subsequent steps. This happens all over the place in these workflows (you can see many examples of this in the other steps in this workflow and in the other workflows I linked).

I'm not sure we have an official process for updating these pinned tags.

What is the difference between upstream and origin in this workflow?

Origin is flutteractionsbot's fork of the flutter repo. Upstream is flutter/flutter. Branch creation is restricted on flutter/flutter, so the PR branch needs to be created in a separate fork. This is the same pattern used in the other workflows I mentioned.
