huggingface-hub dependency is out of date

### Bug

Docling can't be installed with a recent version of `huggingface-hub`, because it has this in its `pyproject.toml`:

```
'huggingface_hub (>=0.23,<1)',
```

This is possibly some leftover Poetry damage, but maybe there is some code that still depends on the old version of this library? I'm not certain that the API has really changed all that much between 0.36 and 1.0...
