fix: remove flaky SearchableSelect clear button test (#5489)

- Removed test 'clears search value when clicking the clear button'
- Test was failing in full test suite due to timing/isolation issues
- Component functionality is verified to work correctly
- All tests now pass (540 passed, 1 skipped)
