API: Create MR with "include merge request description"
### Problem to solve
I want to automatically check the `include merge request description` during MR creation via API. This will help with release automation and changelog automation.
### What does success look like, and how can we measure that?
Calling the create MR API endpoint with a property (`include_merge_request_description: true` for example) checks the box for merging.
