Issue: Validate config name and data_files in packaged modules
State: closed
Author: albertvillanova

Validate the config attributes `name` and `data_files` in packaged modules by making the derived classes call their parent `__post_init__` method.

Note that their parent `BuilderConfig` validates its attributes `name` and `data_files` in its `__post_init__` method: https://github.com/huggingface/datasets/blob/60d21efbc01e15d0b596ac1072750cbecd91548a/src/datasets/builder.py#L128-L137

This PR makes the derived config classes call their parent `__post_init__` method to validate their `name` and `data_files` attributes.

I pushed a change that fixes 2.15 cache reloading (I fixed the packaged module hash), feel free to merge if this change is fine for you

Something weird happened in GitHub: I just merged this PR to main, See: https://github.com/huggingface/datasets/commit/5bbbf1b19766e31a6905f3e82bf3aa3f9f84a982

However this PR still appears as Open...

If I retry to merge this PR, an error appears: "Merge attempt failed: Merge already in progress"
