Submit Music Cover Generation Task
  1. After submission, a task_id will be returned. If you provided a callback_url, when the task status becomes finished or failed, a POST request will be sent to the callback_url.
  2. Regardless of whether callback_url is provided, you can retrieve the response result through the unified Query Music Detail endpoint.
