marge-bot-mesa: remove --add-reviewers option
The upstream --add-reviewers --keep-reviewers option needs some fixes in upstream marge-bot. It is having trouble finding the email address of users who have reviewed the merge request. It is adding noise to commit messages by adding "<None>" instead of email addresses as expected. It is also not using the commit_email address that developers may set to keep their gitlab user email address private.
Remove this option in mesa/mesa until it is fixed upstream.
Example: mesa/mesa@308c2b98

Sorry for the trouble with this feature.
