Sharpen type annotation of `_get_arg_id_to_arg_and_arg_id_to_descr`

According to the type listed `args: tuple[Any, ...]`, args should be able to support an object type. However, it does not. Passing in an object that is not an `pt.Array` or `scalar` or `ArrayContainer` returns an error message. I think we should just return the descriptor as the position of the object within the `args` tuple.

找到 `_get_arg_id_to_arg_and_arg_id_to_descr`，檢查它如何處理 `args` tuple 中的項目，尤其是既不是 `pt.Array`、`scalar` 也不是 `ArrayContainer` 的物件。確認對一般物件的預期行為，接著讓 descriptor 使用該物件在 `args` 中的位置，並驗證回報的錯誤不再發生。
