fix(query-core): widen QueriesObserver queries type (#7446) (#7492)

* fix(query-core): widen QueriesObserver queries type (#7446)

Widen the `QueriesObserver` queries type so we can assign `UseQueryOptions` to `QueryObserverOptions`.

The result from the `queryOptions` helper can now be passed to `QueriesObserver`.

* chore: prettier

* fix(types): QueryKey needs to default to `any`, too
