# To modify this workflow:
#
#  - push it to the wip-ci-end-to-end branch on the forgejo repository
#    otherwise it will not have access to the secrets required to push
#    the cascading PR
#
#  - once it works, open a pull request for the sake of keeping track
#    of the change even if the PR won't run it because it will use
#    whatever is in the default branch instead
#
#  - after it is merged, double check it works by setting the
#    run-end-to-end-test on a pull request (any pull request will doe
