dutch_social can't be loaded
@lhoestq could you also shed light on the Hindi Wikipedia Dataset for issue number #1673. Will this also be available in the new release that you committed recently?
Hi all,

I'm trying to import the `dutch_social` dataset described [here](https://huggingface.co/datasets/dutch_social).

However, the code that should load the data doesn't seem to be working, in particular because the corresponding files can't be found at the provided links.

 @lhoestq could you also shed light on the Hindi Wikipedia Dataset for issue number #1673. Will this also be available in the new release that you committed recently?
