[Types]: type of parent should be Parent

[christianvoigt]

Hi, currently the type for Visitor is

  type Visitor<V extends Node> = (
    node: V,
    index: number,
    parent: Node
  ) => void | Action | Index | ActionTuple

I think the parent parameter should be of type Parent, as the type Node does not have a children property.
