# Check for the presence of a PROJEN_GITHUB_TOKEN secret. | |
# | |
# This is expected to contain a personal access token of someone who has | |
# permissions to bypass branch protection rules. | |
# | |
# If not present, we can only use GitHub Actions Token permissions, | |
# but this has the following downsides: | |
# | |
# - Those are bound by branch protection rules (so automated pushing won't work). | |
# - As soon as a workflow file needs to be changed, GitHub will reject the push. | |
# Only Apps and Users can be allowed to modify workflows. | |
