Actually document the `TypedUse*` types

[markerikson]

We have the TypedUse* types (TypedUseQuery, etc) to allow userland typing of things like hooks and hook results, but I don't think we actually describe those in the docs. We should add those.

Hi! 👋

I'd like to work on this issue.

I looked through the existing docs and confirmed that the TypedUse* types
(TypedUseQuery, TypedUseMutation, TypedUseQueryState, etc.) are currently not documented anywhere.

My plan is:

• Add a new section to the RTK Query TypeScript docs that introduces each TypedUse* helper type
• Describe when users may need these types (custom wrappers for hooks, typed API composition, etc.)
• Include short code examples for common use cases
• Add links to the relevant TypeScript source definitions

Does this direction look good to you?
If so, I’ll open a PR. 👍

@semimikoh sure, sounds good!
