Revert: re-enable dataset viewer

Keeping viewer enabled so the dataset preview works on the Hub. Users on datasets<4.7 (e.g. SQuADDS<=0.4.3 installs that pulled datasets>=2.19) should run: pip install --upgrade 'datasets>=4.7' 'huggingface_hub>=0.25'. SQuADDS 0.4.4 will pin datasets>=4.8.1 so new installs are unaffected.
