[Bug]: foreign_class not working with auth token #1678

Describe the bug

Hello,
I am trying to load a custom encoder from a private HuggingFace model with foreign_class but am faced with the following issues.

1. It seems use_auth_token is not properly passed here:
   

   speechbrain/speechbrain/pretrained/interfaces.py

   Lines 91 to 92 in 64c8fa9

   	hparams_local_path = fetch(hparams_file, source, savedir, use_auth_token)
   	pymodule_local_path = fetch(pymodule_file, source, savedir, use_auth_token)

   
   That is because use_auth_token is the sixth parameter in fetch and as such should be called like:

   fetch(hparams_file, source, savedir, use_auth_token=use_auth_token)
   

   By changing that I was able to download the custom encoder.py and hyperparams.yaml

2. Authentication fails again while trying to fetch the model checkpoints during collect_files of the Pretrainer:
   

   speechbrain/speechbrain/utils/parameter_transfer.py

   Lines 202 to 204 in 64c8fa9

   	path = fetch(
   	filename, source, self.collect_in, save_filename=save_filename
   	)

   
   Where there seems to be no option to pass the auth token.

Expected behaviour

Passing the HuggingFace access token in foreign_class(..., use_auth_token={token}) should authenticate and download the required files.
