Add support for the Draft prefix out-of-the-box

About this issue

As per this GitLab post regarding the migration of GitLab SaaS to GitLab 14.0:

WIP (work in progress) status for merge requests provide a clear signal to reviewers that the merge request in question is not ready to be merged. The WIP feature for merge requests has been renamed to "Draft", a more inclusive and self-explanatory term. "Draft" clearly communicates the merge request in question isn't ready for review, and makes no assumptions about the progress being made toward it. "Draft" also reduces the cognitive load for new users, non-English speakers, and anyone unfamiliar with the WIP acronym.

WIP merge requests were deprecated in favor of draft merge requests, and are removed entirely in GitLab 14.0.

While this might be nonsense for non-GitLab users (particularly the ones who never used the SaaS version or never ever switching to GitLab for some), this is just heads up btw.

Thanks! I don't think we would support "draft" out-of-the box because

1. The app itself is called WIP
2. The risk for more false positives

But I'll leave the issue open for a bit in case anyone has more input about this
