⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Add regression coverage for aria-labelledby + default aria-label coexistence.

These tests cover default and custom label values, but they don’t lock the third behavior this PR depends on: when only aria-labelledby is provided, aria-label="Contents" should still be present.

Suggested test addition 
 test('uses a custom aria-label when one is provided', () => {
   render(<Spinner aria-label="Loading users" />);
   expect(screen.getByRole('progressbar')).toHaveAttribute('aria-label', 'Loading users');
 });

+test('keeps default aria-label when aria-labelledby is provided', () => {

+  expect(spinner).toHaveAttribute('aria-label', 'Contents');

In `@packages/react-core/src/components/Spinner/__tests__/Spinner.test.tsx` around
lines 9 - 17, Add a regression test in Spinner.test.tsx that renders <Spinner
aria-labelledby="some-id" /> and asserts that screen.getByRole('progressbar')
has both aria-labelledby="some-id" and the default aria-label="Contents"; update
the test suite by adding a new test case (similar to the existing ones) to
exercise the coexistence of aria-labelledby and the default aria-label so the
Spinner component preserves aria-label when only aria-labelledby is provided.
