Update labels from backstage to feature::maintenance
Description
Update the labels applied with Renovate MRs like gitlab-org/gitlab!36689 (merged) which I believe are re-creating the ~"backstage"
label on the project level. https://gitlab.com/gitlab-org/gitlab/-/labels/15614818/edit is an example of the current project level ~"backstage"
Issues: https://gitlab.com/gitlab-org/gitlab/-/issues?label_name%5B%5D=backstage Merge Requests: https://gitlab.com/gitlab-org/gitlab/-/merge_requests?label_name%5B%5D=backstage
The first item created was gitlab-org/gitlab!36689 (merged) which I believe had the label created when the MR was opened.
backstage [DEPRECATED] has been deprecated as apart of https://gitlab.com/gitlab-org/quality/team-tasks/-/issues/488
