Adds a response with id and label to this.
Responses are represented as buttons in the dialog.
Response ID must be unique. It will be used in [signal@AlertDialog:AdapAlertDialog:response] to tell which response had been
activated, as well as to inspect and modify the response later.
An embedded underline in label indicates a mnemonic.
[method@AlertDialog.set_response_label] can be used to change the response label after it had been added.
[method@AlertDialog.set_response_enabled] and [method@AlertDialog.set_response_appearance] can be used to customize the responses further.
