exposes all types

[kotarella1110]

Summary

This PR exposes all types of React on Rails. There are two main reasons for this:

Firstly, I frequently use types such as RenderFunction and RailsContext and would like to import them with minimal code:

- import { RenderFunction, RailsContext } from "react-on-rails/node_package/lib/types";
+ import { RenderFunction, RailsContext } from "react-on-rails";

Additionally, since railsContext is customizable, exposing the RailsContext type allows for extensions like the following:

react-on-rails.d.ts:

declare module "react-on-rails" {
  interface RailsContext {
    key1: string;
    key2: string;
  }
}

export {};
