Describe the feature or problem you’d like to solve

As the title suggests, using the --edit-last flag for gh pr comment will return no comments found for the current user and fail

One way to circumvent this is to check for existing comments and either comment if no comment already exists or --edit-last if one comment exists

But to me it'd make more sense for the flag to have the logic inside

Proposed solution

While this makes sense, what would possibly make more sense is to comment anyway if no comment is found, as this would be the first comment for the user, and then indeed it'll get edited in the future using the flag
