Different Results on Different Platforms: `array_distinct`
The `array_distinct` function may return results [in a different order on different platforms](https://github.com/duckdb/duckdb/issues/13746):  
```sql
SELECT array_distinct(['A', 'A', 'B', NULL, NULL]) AS arr;
```  
For this query, both `[A, B]` and `[B, A]` are valid results.
