Currently PruneColumns inherits from ParquetTypeVisitor which will only pass Parquet types. Later when we add the support for Variant type, we need to know the column is a Variant type during column pruning. Before logical Variant type is added to Parquet, we can change to inherit from TypeWithSchemaVisitor to have the Iceberg type. #11178
Existing tests in TestPruneColumns should provide the test coverage so no tests are added.
