Copy merge request routes to - scope
What does this MR do?
Another approach to !21126 (merged) and #118849 (closed)
Copy merge request routes under -
scope so GitLab can serve both at the same time. We need this so, when we deprecate unscoped path, we can do a canary deploy without people getting 404. See !22082 (comment 262919897) for details
Does this MR meet the acceptance criteria?
