Reduce duplication with `slugifyWithUnderscore` and `slugify` in `text_utility`
(Identified in https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/10570/diffs#note_182240546)
Problem to solve
We have two text utility functions which are doing something very similar. Could we somehow combine these? Would that break the expectations of any of the clients of slugifyWithUnderscore
?
