Corrective Action: Update QA issue to ping release managers when a bug was found
When a bug is found during QA there's not a clear direction of what are the next steps a developer should take, this has lead to messages getting lost and deployments triggered with the bug in it (As an example https://gitlab.com/gitlab-org/release/tasks/-/issues/1464#note_381147044)
