Add ability to sort Dependency List by Severity

See merge request gitlab-org/gitlab-ee!14567

This adds "Severity" to the available sorting options on the Dependency
List. This will sort the dependencies according to the severity of any
of their detected vulnerabilities.

This contributes towards the larger [feature][1] for adding dependency
scanning results to the Dependency List, behind the
`dependency_list_vulnerabilities` feature flag.

This fixes the problem by sorting the expectation by
reference string too
