Fix RadioGroup tests to match new architecture

Updated RadioGroup tests to match the refactored component:
- RadioGroup now renders div container (removed fieldset/legend tests)
- Removed legend and hideLegend prop tests
- FormFieldset component should be tested separately for fieldset/legend behavior

All 613 tests now passing ✅
