Improve DependencyLinker sanitization

What does this MR do and why?

Improves performance of our dependency linkers. This skips the unnecessary HTML parsing that sanitize does.

To test this, I copied the contents of this file and committed to a local repo in GDK.

Then I loaded http://127.0.0.1:3000/gitlab-org/gitlab-test/-/blob/master/go.sum?format=json&viewer=simple
