Pre-reqs for 'Pipelines for Merged Results' Doesn't Mention GitLab Repo Requirement
https://docs.gitlab.com/ee/ci/merge_request_pipelines/pipelines_for_merged_results/ doesn't specify in the list of Prerequisites that the repository must be a GitLab repository, which seems to be the case, since I can't find the "Settings > General > Merge request" option for my external GitHub project.
