fix: add union type aliases for response types in generated exports

The types/__init__.py expects CreateMediaBuyResponse, UpdateMediaBuyResponse,
and SyncCreativesResponse as imports, but after schema regeneration only the
numbered variants (Response1/Response2) exist.

This fix adds union type aliases (Response1 | Response2) to the consolidate
exports script so these types are available after regeneration.
