[Bug]: Windows saving of hugging face models fails due to using the / Override on a WindowsPath Object

[dsamford]

Describe the bug

Hugging Face models can't be downloaded using fetching.py

Expected behaviour

The destination variable is initialized correctly on windows.

To Reproduce

vad_model = VAD.from_hparams(source="speechbrain/vad-crdnn-libriparty", savedir="pretrained_models/vad-crdnn-libriparty")
