SSR example misuses React Router v6

[is2ei]

Describe the bug

I was trying to use SSR example.
/~https://github.com/vitejs/vite-plugin-react/tree/v4.1.0/playground/ssr-react

What I expect is that the example works correctly.

What actually happening is that the example misuses React Router v6 as if it is v5.
React Router v6 has breaking changes but the commit 1ea4577 did nothing with that.

For example, it uses context prop on StaticRouter

/~https://github.com/vitejs/vite-plugin-react/tree/v4.1.0/playground/ssr-react/src/entry-server.jsx#L7

But StaticRouter doesn't have context prop.
