SST-582 Add information on how to mark a Merge Request as draft.
Due to a [breaking change coming in Gitlab 14.0|https://about.gitlab.com/blog/2021/06/04/gitlab-moving-to-14-breaking-changes/], Using WIP in the description of a Merge Request will no longer mark the Merge Request as not ready yet. The motivation for the change is that WIP is an acronym that takes time to parse, and is even more inaccessible to non-native English speakers.
