     Creates the repository `$forgejo/root/myaction` and populate it with the
     content of the repository under test, except for the `.forgejo` directory
     (it would otherwise create an infinite recursion loop). The tag `vTest` is
     set to the SHA under test.

     Create the repository `$forgejo/root/testrepo` and populate it with the
     content of the `testrepo` directory. All occurrences of `SELF` in
     `testrepo/.forgejo/workflows/*.yml` are replaced with `$forgejo/root/myaction`.
