When customizing the save path, modify the "save_details" location

[Guncuke]

If the local model path is used, such as /mnt/public/xxxx, and the results_path_template is not specified, the path for saving the results will be extremely long and the directory will be difficult to read.

Now, we can specify the results_path_template so that the files will be saved in the corresponding path. However, if save_details is specified, the details will still be saved in the original path, which is not convenient for reading the parquet corresponding to the details. Therefore, I change that under the condition that the user specifies the saving path, the details can also be placed in the corresponding directory.
