Dataset Viewer issue for CSV datasets

### Description

I'm populating CSV datasets [here](https://huggingface.co/scikit-learn) but the viewer is not enabled and it looks for a dataset loading script, the datasets aren't on queue as well. 

You can replicate the problem by simply uploading any CSV dataset.
