Fix DDL test assertions to match actual compiler output

Fix MAP type assertions to include spaces in generated DDL:
- MAP<STRING,STRING> -> MAP<STRING, STRING>
- MAP<STRING,INTEGER> -> MAP<STRING, INTEGER>

This matches the actual SQLAlchemy compiler output which includes
spaces after commas in type parameter lists.

Fixes CI test failures:
- test_create_table_with_map_types
- test_create_table_with_struct_types (nested MAP parts)
- test_create_table_with_complex_nested_types
