docs: fix typo/outdated hook reference (#2324)

According to the link below, useQueryCache was replaced by
useQueryClient in react-query 3.

https://react-query.tanstack.com/guides/migrating-to-react-query-3#the-usequerycache-hook-has-been-replaced-by-the-usequeryclient-hook

I update the wording here using the wording in useHydrate.md as a
reference.
