Modernize merge button (#28140)

Browse source 
- Make use of the `form-fetch-action` for the merge button, which will
automatically prevent the action from happening multiple times and show
a nice loading indicator as user feedback while the merge request is
being processed by the server.
- Adjust the merge PR code to JSON response as this is required for the
`form-fetch-action` functionality.
- Resolves https://codeberg.org/forgejo/forgejo/issues/774
- Likely resolves the cause of
https://codeberg.org/forgejo/forgejo/issues/1688#issuecomment-1313044
