[Docs]: Document Route.ComponentProps

[timdorr]

Describe what's incorrect/missing in the documentation

TIL, there are now props passed to the Component default in a route module. These simplify things a bit from having to import the hooks and hook up the type generics on your own. Lots of boilerplate is now gone!

We should probably, you know, tell people that 😄 I would suggest expanding this section: https://reactrouter.com/start/framework/route-module#component-default
