Subject: [PATCH] test(eslint-plugin-query/no-void-query-fn): add coverage for
 useInfiniteQuery, useSuspenseQuery, queryOptions, fetchQuery

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.
