text: Title: Trouble Loading a Gated Dataset For User with Granted Permission
  Body: ### Describe the bug
  
  I have granted permissions to several users to access a gated huggingface dataset. The users accepted the invite and when trying to load the dataset using their access token they get 
  `FileNotFoundError: Couldn't find a dataset script at .....` . Also when they try to click the url link for the dataset they get a 404 error.
  
  ### Steps to reproduce the bug
  
  1. Grant access to gated dataset for specific users 
  2. Users accept invitation
  3. Users login to hugging face hub using cli login
  4. Users run load_dataset
  
  ### Expected behavior
  
  Dataset is loaded normally for users who were granted access to the gated dataset.
  
  ### Environment info
  
  datasets==2.15.0
