Danger: docs-only change should not prompt for Changelog

https://docs.gitlab.com/ee/development/changelog.html#what-warrants-a-changelog-entry

  • Any docs-only changes should not have a changelog entry.

Problem

I am being prompted for a changelog in my docs only MR - https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/32306#note_208923341

Proposal

Detect if MR is docs-only. If so, skip the Changelog prompt
