Cover the exact CI fuzzer query in the regression test

Add the query shape the AST fuzzer aborted on in the `amd_msan` stress
test of ClickHouse#108685 (multi-column
projection with a correlated scalar subquery over a `GROUPING SETS` key
under `WITH TOTALS`), scaled down and deterministic, so the regression
test ties directly to the reported failure.
