Release #31

	# A Workflow for triggering a new release.
	#
	# Releasing is a two stage process.
	# 1. Running this workflow will check the build is green and then push a release tag to the repo, e.g. v1.2.3
	# 2. Pushing the release tag (e.g. v1.2.3) will trigger the main CI build.yml.
	# This main build has conditional steps that only run, or only don't run, when building a release build, i.e. a build triggered when a release tag is pushed.
