Resolve Conversation with Commit

When working through a review, I like to resolve conversations with one commit per conversation request. Right now the workflow is pretty cumbersome, I create the commit via vscode source editor, then copy the commit ID, then paste it into the conversation request as "Resolved" and finally close the issue.

I would like a "Fix with Commit" button on a conversation that will take my staged changes (or all changes if none staged) and once clicked, automate these steps:

1. Commit to the PR
2. Update the conversation where the button was clicked with a new "Resolved " comment
3. Resolve the conversation.

この issue には実装ファイル、テスト、エントリーポイントが記載されていません。まず、extension に既存の conversation actions と commit/PR の更新フローを追跡してください。action が staged changes またはすべての変更を commit し、conversation に commit ID を投稿して、それを解決すれば完了です。
