Delete stale branches after 1 month of closed/merged MR or 3 months of Inactivity Consider closing MRs after 1 month of inactivity, deleting the branch after 2 months similar to https://gitlab.com/gitlab-com/www-gitlab-com/-/tree/master/scripts We should also consider standardizing with the `gitlab-org/gitlab` project. Current implementation is 3 months: https://gitlab.com/gitlab-com/content-sites/handbook-tools/triage-bot/-/blob/main/.triage-policies.yml?ref_type=heads#L104 See also https://gitlab.com/gitlab-org/quality/engineering-productivity/team/-/issues/567#note_2169291952 for how the `gitlab` project was cleaned up of stale branches.
