# By default, workflows can't trigger other workflows when they're just using the
# default `GITHUB_TOKEN` access token. (This is intended to stop you from writing
# recursive workflow loops by accident, because that'll get very expensive very
# quickly.) Instead, you have to manually call out to another workflow, or else
# make your changes (i.e. the `git push` above) using a personal access token.

# Note: we use $GITHUB_REF here to run PR against the merge of this change with
# develop; use github.event.pull_request.head.ref above to commit to the PR
