custom exception for dataset script errors in job runners
Part of https://github.com/huggingface/datasets-server/issues/1443 for:
Many errors are due to the dataset script error, unrelated to the job runners' logic.
Adding script error recognition at the job manager level based on stack trace content. All of the issues related to the dataset follow the pattern `datasets_modules/datasets`. 
I think this will help us separate the external errors from ours.
