Unapprove quick action
Problem to solve
Follow-up to https://gitlab.com/gitlab-org/gitlab-ee/issues/1873
A reviewer may approve a merge request using quick actions. However, they may spot problems later that mean they want to revoke that approval.
Further details
This may particularly be a thing while using batch comments. Say at comment 4, they use /approve, then notice something that causes them to add another comment. Rather than going back and editing comment 4 to remove /approve, it would be awesome to be able to just add /unapprove to the following comment.
Proposal
Add a /unapprove quick action
What does success look like, and how can we measure that?
Able to remove approval using quick actions
