Upgrade to MinIO 5.0.0 and include built module

- Updated MinIO SDK from 3.1.13 to 5.0.0
- Fixed all compilation errors and warnings for MinIO 5.0.0 compatibility
- Updated API calls to use new Args-based patterns (PutObjectArgs, GetObjectArgs, etc.)
- Fixed type compatibility issues (DateTime, ulong conversions)
- Removed deprecated APIs (WithCancellation, ProgressReport)
- Updated System.Text.Json to 9.0.0 to resolve security vulnerabilities
- Added Module directory to repository with built PSMinIO.dll
- Module is now ready for distribution and testing
- All builds pass with 0 errors and 0 warnings
