Bump version of ubuntu #39

	# cinc-auditor has its own workflow because it is a prerequisite image for enabling
	# the lint stage of our container image pipeline. When we are bootstrapping a new
	# setup, this image will not be present in the container registry, nor will the image
	# be present for running tests. So we avoid running the lint and test stages of the
	# container build pipeline.
