Fix Git version check to handle Windows formatting

- Update Test-GitVersion to properly parse Git versions with Windows suffixes
- Handle formats like '2.52.0.windows.1' correctly
- Parse major and minor version numbers separately for accurate comparison
- Now correctly identifies versions 2.23+ regardless of Windows-specific suffixes
- Add better error message when version parsing fails
