Update macOS build process and enhance artifact finalization

- Replaced the macOS build command in package.json to use a new script for better architecture handling.
- Added a new script for building macOS applications that supports both arm64 and x64 architectures.
- Enhanced the finalize-desktop-artifacts script to improve artifact discovery and cleanup, ensuring proper handling of macOS DMG and app bundles.
- Updated functions to streamline the process of finding and publishing artifacts, improving overall reliability.
