docs: If we're not doing a full run, limit to media uploaded to wordpress 'recently'.
          'Recently' in this case means 90 days before the date we're processing content from.
          The wp.com REST API doesn't have a way to limit based on media modification date,
            but this should be relatively close.
  
          :param params: the GET params dict, which may be updated to include the "after" key
          :return: None (side effect: possibly modified params dict)
