[Docs] Redux with Next.js Per-route state

What docs page needs to be fixed?

• Section: Per-route state
• Page: https://redux.js.org/usage/nextjs#per-route-state

What is the problem?

I'm learning Nextjs and want to setup Redux in Nextjs but this section is not very clear to me Additional Configuration > Per-route state, also the source code is not available in the documentation. It seems as if the documentation is not updated, it doesn't match with the project npx create-next-app --example with-redux my-app.

What should be changed to fix the problem?

Adding an example would be useful to understand why I should initialize the store again, and in what situation I should do it.
