Bot account for gnome-build-meta updater
As a followup to GNOME/gnome-build-meta!1795 (merged) we need to have a bot account to update the refs periodically. @alatiera and I are working on it but we need a bot account to push to the repository.
Ideally this would run in a scheduled pipeline to have access to the cache that is already in the runner but we can have it run on openshift for more security.
