Add workflow labels when tracking deployments
When tracking a deployment, we now add the appropriate environment workflow labels (e.g. workflow::staging) to all the deployed merge requests. We do this for both gitlab-org/gitlab, and gitlab-org/gitaly.
This builds upon the merge request !809 (merged), and the API for viewing deployed merge requests introduced in gitlab!21837 (merged).
