Old link was to a hard-coded link that redirected users to a new url.

New link uses relative path that works in compiled documentation.

merge_request_application_and_rate_limit_guidelines.md becomes

This makes it easier to grok. We are also looking

necessarily the group that owns the feature. Previously that was
not clear in the handbook, so this adds some guidance.
