Add formats tags
Added `formats: list[str]` to "hub-cache". It is computed in "compatible-libraries" since compatibilities depend on the format.

Possibles values are
- csv
- json
- parquet
- text
- imagefolder
- audiofolder

Mentioned in https://github.com/huggingface/datasets-server/issues/2455

I chose to have it as a list for simplicity, but lmk if you think we should set it to `format: Optional[str]` instead

includes a minor change: updated the libraries order
