Spark `arrays_zip` return type is slightly different from DF or DuckDB

```
scala> spark.sql("select arrays_zip(array(1, 2, 3), array(2, 3, 4), array(3, 4, 5))").printSchema
root
|-- arrays_zip(array(1, 2, 3), array(2, 3, 4), array(3, 4, 5)): array (nullable = false)
| |-- element: struct (containsNull = false)
| | |-- 0: integer (nullable = true)
| | |-- 1: integer (nullable = true)
| | |-- 2: integer (nullable = true)
```

whereas DF/DuckDB numeration starts with 1.

The idea is to introduce Spark wrapper on top of DF `arrays_zip` and change return type
