docs: Returns descriptions of what each policy does. This action supports
          pagination. If the response includes a token, there are more records
          available. To get the additional records, repeat the request with the
          response token as the NextToken parameter.
  
          If no group name or list of policy names are provided, all
          available policies are returned.
