fix(git): change auxolotl url to new location

As per https://forum.aux.computer/t/starting-our-migration-to-forgejo/781,
Auxolotl has switched to their own forgejo instance from GitHub.

To maintain compatibility with old repos, aux: will point to *the
organization rather than the instance*. the new 'af' ('auxforge') will
point to the instance
