	# Post-submit and daily build and publish of the Helm chart and Docker container
	# This is a separate workflow than image-build.yml because image-build.yml is
	# run in the PR context, and those runs aren't allowed package:write permissions if
	# the source is a fork(GitHub errors and invalidates the entire workflow if you try).
