Fix deprecation warning when use_auth_token passed to download_and_prepare
The `DatasetBuilder.download_and_prepare` argument `use_auth_token` was deprecated in:
- #5302

However, `use_auth_token` is still passed to `download_and_prepare`  in our built-in `io` readers (csv, json, parquet,...).

This PR fixes it, so that no deprecation warning is raised.

Fix #5407.
