docs: Respond on PUT HTTP request assuming resource update flow.
  
          This request handler assumes that PUT requests are associated with
          resource update/modification. Thus default flow for such requests is:
  
          * Modify existing resource instance and prepare its representation by
            calling its update method handler.
          * Set response status code to ``202 Accepted``.
  
          Args:
              req (falcon.Request): request object instance.
              resp (falcon.Response): response object instance to be modified
              handler (method): update method handler to be called. Defaults
                  to ``self.update``.
              **kwargs: additional keyword arguments retrieved from url template.
