   This is a follow-up for https://github.com/apache/spark/pull/37833.
   
   The PR fixes column names in `arrays_zip` function for the cases when 
`GetArrayStructFields` and `GetMapValue` expressions are used (see unit tests 
for more details).
   
   Before the patch, the column names would be indexes or an AnalysisException 
would be thrown in the case of `GetArrayStructFields` example.
   
   ### Why are the changes needed?
   <!--
   Please clarify why the changes are needed. For instance,
     1. If you propose a new API, clarify the use case for a new API.
     2. If you fix a bug, you can clarify why it is a bug.

   Fixes an inconsistency issue in Spark 3.2 and onwards where the fields would 
be labeled as indexes instead of column names.
