# To modify this workflow:
#
#  - push it to the wip-cascade branch on the 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
#    label on a pull request (any pull request will do)
