feat: Handle both English and German error messages

- Added support to handle Git error messages in both English and German.
- Enhanced the resolve_git_errors method to recognize and resolve common Git errors in multiple languages.
- Ensured that the application can manage errors consistently regardless of the language of the Git error messages.
