Limit to inferior fsspec version

[LysandreJik]

The newly released fsspec version breaks the implementation in transformers' CI, see the following error:

"/home/circleci/.pyenv/versions/3.8.12/lib/python3.8/site-packages/datasets/builder.py", line 1173, in as_dataset
    raise NotImplementedError(f"Loading a dataset cached in a {type(self._fs).__name__} is not supported.")
NotImplementedError: Loading a dataset cached in a LocalFileSystem is not supported.
/home/circleci/transformers/src/transformers/models/beit/modeling_beit.py:737: UnexpectedException

Additionally:
huggingface/datasets#6331

The documentation is not available anymore as the PR was closed or merged.

Issue is datasets-related and will be fixed directly there. Closing this issue without merging :)

EDIT: fixed in huggingface/datasets#6334.
