test(vue-query): strengthen #8199 regression assertion with explicit TData

Per CodeRabbit feedback: bare assertType(useBasket('fruit')) only verified
the call compiled, which would still pass under the old buggy behavior
(TQueryKey collapsing to QueryKey, TData inferred as unknown). Lock the
regression by asserting the propagated TData explicitly.
