Fix macOS onnxruntime dependency conflict

- Change onnxruntime dependency from ==1.22.0 to >=1.19.0,<=1.22.0
- Allows onnxruntime 1.19.2 (supports macOS 11.0+) while maintaining compatibility with 1.22.0
- ChromaDB requires onnxruntime >= 1.14.1, so this range is fully compatible
- Add comprehensive tests to verify macOS compatibility and dependency resolution
- Fixes issue #3202 where CrewAI cannot be upgraded on macOS due to onnxruntime conflicts
