visit API documentation discrepancy

[janmeier]

The docs for visit, https://www.graphql-js.org/api-v16/language/#visit mentions that the API can be called in four different ways.

However, it looks like the implementation only supports three of those. Namely, this is not supported neither by the typescript interface, nor the actual implementation

visit(ast, {
  enter: {
    Kind(node) {
      // enter the "Kind" node
    },
  },
  leave: {
    Kind(node) {
      // leave the "Kind" node
    },
  },
});

I can provide a PR to fix it, but I would like to know which part to fix - The documentation, or the implementation ;)

Thanks for pointing this out! Looks like this functionality was removed some time ago as a form of code simplification within #2957 => so it is the docs that need to be updated.
