MergeRequest API documentation incorrectly lists state_event options
Description
The MergeRequest API documentation lists the options as (close|reopen|merge
), but merge has been moved to a separate endpoint.
Additionally they are not mentioned at all in doc/api/merge_requests.md
since https://gitlab.com/gitlab-org/gitlab-ce/commit/8b5c16e4b1d54745ba6ca65ecfbf14c1683db3b4
