feat: correct struct column names for arrays_zip return type

[comphead]

Which issue does this PR close?

For arrays_zip the return type is slightly different comparing to DuckDB, namely the struct field names are different

DuckDB expects a

struct {
  1: ...., 
  2: ...., 
  3: ...., 
  n: ...... 
}

DF got

struct {
  c0: ...., 
  c1: ...., 
  c2: ...., 
  cn: ...... 
}

Some future work - for Spark the field names are 0 based numeration

struct {
  0: ...., 
  1: ...., 
  2: ...., 
  n: ...... 
}

• Closes #.
