STY: Use endswith instead of logical equals (#2732) #101

	# This action assumes that there is a REL-commit which already has a
	# Markdown-formatted git tag. Hence the CHANGELOG is already adjusted
	# and it's decided what should be in the release.
	# This action only ensures the release is done with the proper contents
	# and that it's announced with a Github release.
