TU Rename

Hi,

In the continuity of the effort started in https://gitlab.archlinux.org/archlinux/tu-bylaws/-/merge_requests/6 and aurweb!755 (merged) regarding the rename of TU to package maintainer, here's an issue to track the related task on the infrastructure side.

• Rename TU in aurweb (aurweb!755 (merged), !762 (merged))
• Rename the bylaws repo from "tu-bylaws" to "package-maintainer-bylaws" (by @klausenbusk)
• Move the bylaw URL to https://package-maintainer-bylaws.aur.archlinux.org and make the former one (https://tu-bylaws.aur.archlinux.org) redirect to it for while (while waiting for every references of this link to be updated). Also update the bylaws repo description accordingly (new name + new url) (02960645)
• Drop the related nginx redirection (which is not so useful anymore) (722cc5bf)
• Rename the archwiki group (!765 (merged))
• Rename the current TU ML from arch-tu@al.org to arch-package-maintainer@al.org and rename "trusted users" to "package maintainers" in the different ML descriptions.
• Make the https://archlinux.org/people/trusted-users/ and https://archlinux.org/people/trusted-user-fellows/ URLs redirect to https://archlinux.org/people/package-maintainers/ and https://archlinux.org/people/package-maintainer-fellows/ (while waiting for every references of this link to be updated) when deploying the new archweb release (see the archweb pr).
• Rename the TU group when deploying the new archweb release (see the archweb pr).

Feel free to add tasks if I missed some. I remain available 😄
