Break apart CI workflows into composite actions #2461

	# what?
	# Checks that a file has been committed under the /.changes directory as a new CHANGELOG entry.
	# Cannot check for a specific filename as it is dynamically generated by change type and timestamp.
	#
	# why?
	# Ensure code changes are reflected in the CHANGELOG.
	#
	# how?
	# This workflow cannot use any secrets since it runs for PRs from forked repos.
	# By default, secrets are not passed to workflows running from a forked repo.
	#
	# when?
	# This will run for all PRs going into main and *.latest under one of the following conditions:
	# - the PR is opened or reopened
	# - any label is added/removed to/from the PR
	# - a new commit is pushed to the branch
	# This will not run if the 'Skip Changelog' label is present on the PR.
