name: Retrigger PRB on ready for review

# When a draft PR is marked ready_for_review, GitHub fires a
# 'ready_for_review' pull_request event but no 'synchronize' event, so
# the Jenkins GHPRB plugin does not re-trigger the PRB-master-job. Post
# the configured GHPRB trigger phrase as a PR comment to kick it off.
#
# pull_request_target (not pull_request) is required so GITHUB_TOKEN
# gets write permissions on PRs from forks - this workflow only posts
# a fixed comment string, so the usual pull_request_target risk
# (executing untrusted PR code with elevated privileges) does not apply.
