URL: https://github.com/apache/datafusion-comet/issues/4684
> in Apache Spark, the ElementAt supports Map, and Comet gates for Array
only, we should support Map
>
> ```
> override def inputTypes: Seq[AbstractDataType] = {
> (left.dataType, right.dataType) match {
> case (arr: ArrayType, e2: IntegralType) if (e2 != LongType) =>
> Seq(arr, IntegerType)
> case (MapType(keyType, valueType, hasNull), e2) =>
> TypeCoercion.findTightestCommonType(keyType, e2) match {
> case Some(dt) => Seq(MapType(dt, valueType, hasNull), dt)
> case _ => Seq.empty
> }
> case (l, r) => Seq.empty
