Refactor test setup to use dynamic import for cleanup function

- Updated the test setup file to use an asynchronous dynamic import for the cleanup function from @testing-library/react.
- This change improves compatibility and ensures that cleanup is only called when the library is available, enhancing the robustness of the test environment.
