fix: update version

- Replace the checkbox "Générer uniquement des multiplications" with radio buttons for "Multiplications uniquement" and "Multiplications ET divisions"
- Update JavaScript code to handle radio button values instead of checkbox
- Maintain backward compatibility with old localStorage format
- Ensure all functionality remains intact
