Fix merge request JSON payload
This PR fixes the JSON payload for merge requests in the Webhook events documentation. Two minor changes were made to the current documentation:
- Add a missing comma after the
draft
object - Remove an extra comma after the
last_edited_by_id
object
I don't know if there will be a subject-matter expert in this case, since the changes are small. Please comment below if I am missing anything.
