[Feature Request] Provide a Typescript snippet code in the examples

In this section you provide only the JS example, however, some developers tend to use Typescript with React-Native. I'd recommend an alternative TS snippet code.

The Javascript Example

import 'react-native-gesture-handler';
import * as React from 'react';
import { NavigationContainer } from '@react-navigation/native';

export default function App() {
  return (
    <NavigationContainer>{/* Rest of your app code */}</NavigationContainer>
  );
}

从链接的 Getting Started 部分开始，具体查看“Installing dependencies into a bare React Native project”，并对比其中现有的 JavaScript 示例。在该处添加一个等效的 TypeScript 代码片段；当该部分同时呈现 JavaScript 和 TypeScript 示例时，文档工作即完成。
