Default config first
Show the default config first in the Viewer.

I did this by ordering the configs in `dataset-config-names` to have the default config in first position

fix https://github.com/huggingface/datasets-server/issues/2541

No need to recompute all the entries, it's fine to apply this to new / updated datasets imo
