[Docs]: Tutorial: React Router library mode

[brookslybrand]

Describe what's incorrect/missing in the documentation

Using React Router as your routing library is just as viable as using it as your framework

However, we are lacking a dedicated React Router (library mode) tutorial like we had in the v6 docs.

We could just copy this existing one, however, createBrowserRouter is less preferred these days (unless you're building a custom framework), so maybe one that focuses more on the component-driven routing would fill the gap
