DisableAQECometAsyncShuffleSuite test columnar shuffle on array is failing when calling comet::execution::shuffle::row::builder_to_array due to:

org.apache.comet.CometNativeException: called `Result::unwrap()` on an `Err` value: InvalidArgumentError("Incorrect datatype for StructArray field \"_2\", expected List(Field { name: \"element\", data_type: Int32, nullable: true, dict_id: 0, dict_is_ordered: false, metadata: {} }) got List(Field { name: \"item\", data_type: Int32, nullable: true, dict_id: 0, dict_is_ordered: false, metadata: {} })")
