WMDE has failed to request those three in T357697, but those repositories are obsolete WMDE analytics repositories that are no longer used and should be archived.

Deleting github mirrors seems to be a procedure, and that is fine with WMDE then.
- [ ] Empty repository, leaving only the README indicating the repo is archived, and referring to this task by URL.
- [ ] Mark the repository read-only in Gerrit (also edit description to prepend "[ARCHIVED]" and a reference to this task, remove all access lists and reparent on `All-Archived-Projects`)
- [ ] Deactivate the Diffusion repository
- [ ] Delete the GitHub mirror
