doc: async_hooks.createHook promiseResolve option

Document the `promiseResolve` option to `async_hooks.createHook()`.

This seems to have been overlooked in commit b605b153 ("async_hooks:
support promise resolve hook") from September 2017.

It is documented elsewhere in the async_hooks API documentation, except
where you actually pass it in.
