chore(deps): update docker/login-action digest to 327cd5a #311

	# This workflow checks that the contents of the PR are ready for
	# publishing as soon as they land in `main`. Most importantly it
	# checks that a new version number has been assigned as part of the
	# change and it's basically consistent with our release policy.
