Pull request overview
This PR fixes the handling of optional request bodies in the OpenAPI Python client generator. Previously, optional bodies were incorrectly treated as required, causing them to always be included in requests. The fix ensures that optional bodies (where requestBody.required is false or missing) are properly typed with Unset, default to UNSET, and are only included in requests when explicitly provided.
Key Changes:
- Modified body parsing to respect the required field from request body definitions
- Updated all property transform templates to support a skip_unset parameter for conditional UNSET initialization
- Added deduplication of union types to prevent duplicate type members
- Generated code now properly handles optional bodies across different content types (JSON, multipart, octet-stream, etc.)
