Fix typo re: pipelines for MRs & enable on .com
This corrects two issues for https://gitlab.com/gitlab-org/gitlab-ce/issues/15310:
- Typo with
merge_requests
keyword (was shown asmerge-requests
) - Now that https://gitlab.com/gitlab-com/gl-infra/infrastructure/issues/5792#note_126397969 is complete, update to show that this feature is available on .com
