[CI] Ensure cleanup can run when Review stage fails
Summary
Adds 'needs: []' to the stop_review_template job so that if the
review stage fails, cleanup jobs can still be triggered.
This should be considered a temporary workaround until an official fix is found. See:

Testing
In https://gitlab.com/gitlab-org/cloud-native/gitlab-operator/-/pipelines/373975193, the Review stage failed. However, the cleanup jobs could still be triggered (i.e. they didn't show This job has been skipped).
