Bump datasets package

The detector in packagehallucination is erroring out:

  File "/home/ec2-user/anaconda3/envs/py3.11/lib/python3.11/site-packages/garak/detectors/packagehallucination.py", line 52, in detect
    self._load_package_list()
  File "/home/ec2-user/anaconda3/envs/py3.11/lib/python3.11/site-packages/garak/detectors/packagehallucination.py", line 44, in _load_package_list
    pypi_dataset = datasets.load_dataset(self.pypi_dataset_name, split="train")

    ds = builder_instance.as_dataset(split=split, verification_mode=verification_mode, in_memory=keep_in_memory)
         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/ec2-user/anaconda3/envs/py3.11/lib/python3.11/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.")

Turns out this is due to a breaking change in fsspec, which is propagating to garak through the datasets dependency.

Solution is to bump datasets.

Can you sync up requirements.txt to this? The tests should pick it up (python3 -m pytest tests/test_reqs.py). Wrote a local fix then realised I don't have access to your branch

[leondz]

also bump requirements.txt datasets ver

[leondz]

Looks like it recently broke again and the current magic version spec is

datasets>=2.14.6,<2.17

[shubhobm]

Updated versions in both places.
