Extract version parsing to shared function and improve error handling

- Created Get-VersionChangeType function in scripts/utils.ps1 (DRY principle)
- Updated vendor.yml and update.ps1 to use shared function
- Fixed numeric comparison for COUNT_UPDATED (fromJSON for proper numeric eval)
- Improved git operation error handling with proper exit code checking
- Only reset commit if it succeeded but push failed
