GH Action bug: If reviewers already assigned, more keep being added

[carlisia]

Issue with our auto assign PR reviewers GH action: It works fine until there's an additional operation to the PR, like changing its state to/from WIP, or, very common, adding additional commits.

This happens now that we are limiting the number of reviewers to a subset of the total.

This is a known issue with the GH Action:

kentaro-m/auto-assign-action#16

I'll keep an eye for this fix and update it in our repos.

Could we minimise the impact of this by changing the trigger to not include synchronize? My understanding is that by including that event, this job will run again on every push.

I think we'll still encounter this issue if we re-run the checks for the PR, but this should at least stop it being triggered on every push.

Looking at our actions, we also have the PR labeler job within the file for assigning PRs. I think we want that job to run on every push, so we should separate that out into a different action.

Def worth it trying the first, and def a yes for the second. Let me try to improve this. Thanks for taking a look @zubron.

Close it, feel free to reopen if the issue still happens again.
