test(eslint-plugin-query/no-void-query-fn): add coverage for useInfiniteQuery, useSuspenseQuery, queryOptions, fetchQuery (#10332)

The existing tests only exercised useQuery. The rule checks any object
property named queryFn, so it applies equally to useInfiniteQuery,
useSuspenseQuery, queryOptions(), and queryClient.fetchQuery(). Add
valid + invalid cases for each to document and lock in that behavior.
