Use a path for the related merge requests endpointsh-fix-related-merge-requests-path

Hosts using a non-standard configuration may have a different
hostname/port/scheme than what may be configured on the GitLab
server. While expose_url should generate a proper URL, there are cases
where it may not work. Since we don't need the full URL, we can use the
relative path.
