docs: Implementation of mandatory interface for traversing the whole rule tree.
          This method will call the implementation of :py:func:`pynspect.rules.RuleTreeTraverser.binary_operation_logical`
          method with reference to ``self`` instance as first argument, with the
          result of traversing left subtree as second argument and with the result
          of traversing right subtree as third argument. The optional ``kwargs``
          are passed down to traverser callback as additional arguments and can be
          used to provide additional data or context.
  
          :param pynspect.rules.RuleTreeTraverser traverser: Traverser object providing appropriate interface.
          :param dict kwargs: Additional optional keyword arguments to be passed down to traverser callback.
