Describe the issue

When trying to merge a PR in GitButler with a method that is not allowed in your GitHub repository's settings, GitButler will do nothing and output no error.

How to reproduce (Optional)

1. Create a repository and turn off "Allow rebase merging" and "Allow merge commits"
2. Make some changes and create a PR with GitButler
3. Attempt to merge the pull request using a default option
4. Nothing happens
5. Switch the method to squash, squash and merge
6. It works

Expected behavior (Optional)

GitButler should grey out these options like on the web PR view.

Relevant log output (Optional)

Thanks a lot for reporting!

Maybe as a start we could look into why failures to interact with forges don't propagate so they are user-observable. Maybe there even is a general way of tackling this, but @estib-vega certainly has ideas as well.
