Describe the feature or problem you’d like to solve

gh repo edit allows setting most properties of octokit.rest.repos.update. But, it doesn't seem to have an option for squash_merge_commit_* properties that I can find.

From the docs and the OpenAPI types, that's:

• squash_merge_commit_message
• squash_merge_commit_title

Proposed solution

Could we be able to set those properties in gh repo edit too, please? I.e.:

gh repo edit --squash-merge-commit-message "PR_BODY" --squash-merge-commit-title "PR_TITLE"

Additional context

Is there precedent for what does or doesn't get implemented in gh repo edit?
