Show equivalent push options at bottom of create merge request page
### Problem to solve
While [push options](https://docs.gitlab.com/ee/user/project/push_options.html#push-options-for-merge-requests) is a very powerful feature, it can be [opaque and hard to use](https://news.ycombinator.com/item?id=31010933) even for folks who are [relatively versed](https://news.ycombinator.com/item?id=31021991) with GitLab and the command line.
It also can be a [hard to discover](https://news.ycombinator.com/item?id=31021852) feature.
### Proposal
Add the equivalent push option command line at the bottom of the `{group}/{project}/-/merge_requests/new` For example:

This could get rather long, so maybe under an expand / click to show method from a UX perspective would be better?
