[Docs]: hints and tips on deployment/production

[Sammeeey]

Describe what's incorrect/missing in the documentation

A topic that's missing in the docs from my point of view is the deployment.
Using React Router locally is pretty straight forward.
But implementing and getting an app working in production isn't.
Building the app from the tutorial works well locally.
Once you go to production, you'll face routing issues because react router does the client-side routing.
But the server doesn't know about the routes.

Inspiration for docs about building for production can be found in the docs of viteJs.
From my point of view they did a great job.
Maybe one could implement something similar for the docs of react router (or at least mention the expected issue that react router doesn't work in production out of the box and give some sources to handle production well).
