Fix uploading win32 libs to huggingface (#2537)

This PR fixes the uploading process for win32 libraries to Hugging Face by updating Windows OS detection and correcting the file copy destination path.

- Replaces deprecated wmic command with PowerShell-based OS detection for better reliability
- Adds fallback mechanism using cmd /c ver when PowerShell is unavailable
- Corrects the destination path for win32 library archives to include version subdirectory
