* RFD 0029 : Move GitHub review bot to shared-workflows repository
Apart from relocating the code to a different location and renaming the package, this
is a no-op change
Depends-on: gravitational/shared-workflows#12
* remove mentions of the GitHub review bot from Makefile targets
Re-run the assign workflow whenever a review is submitted.
If the PR meets the required approvals and there are additional
reviewers still assigned, dismiss them.
This makes it easier on reviewers to filter PRs on
"awaiting review from me" as the list will not include PRs that
already have the required reviews.
Fixes#11855
Code reviewers are split into code owners and code reviewers. Each PR is
now randomly assigned a reviewers from the code owner and reviewer set.
Review checking makes sure that a reviewer from each set has approved
the PR.
