Action occasionally fails with #ERROR# HttpError: Validation Failed

[konradpabjan]

I've noticed this action fail a few times with this error with some repositories that use it.

This action should add a more robust retry mechanism to ensure this doesn't happen.

I recently ran into this error on a few repos. It was deterministic which repos it occurred on, and the root cause was because the token I was using didn't have triage access to those repos.

I agree that a more robust retry mechanism would be good, and I also would have benefitted from more error logging: when and why the validation error occurred, for example.

We are getting this error regularly on one of our repositories with the move-labeled-or-milestoned-issue action.
