Docs: Fix some words misspelling.

[DemaPy]

What is the improvement or update you wish to see?

Reading NexJs amazing documentation I have found some mistake in word.

Import useRouter and usePathname from 'next/navigation', and use the replace method from userRouter() inside handleSearch:

Chapter 11

Is there any context that might help us understand?

It would be nice to update it, since NextJs doesn't have this type of hook.

Developers will try to use it, and will have a problem.

Does the docs page already exist? Please link to it.
