docs(toolkit): fix `LazyInfiniteQueryTrigger` docs

[aryaemami59]

• fix LazyInfiniteQueryTrigger docs mentioned by this comment in fetchNextPage always triggering onQueryStarted, even when queryFulfilled already occured. #5167.

I opened a docs PR for this here:

#5261

It fixes the copied LazyInfiniteQueryTrigger description and adds an explicit useInfiniteQuerySubscription signature so the direction argument is documented correctly.
