docs: Get the current default `Plugin` or command predicate. If the
              `cmd` argument is `True`, the current command predicate is
              returned if set, otherwise the default `Plugin` predicate
              will be returned (which may be `None`).
  
              If no default predicate is set and a `pred` value is passed
              it will be returned.
