Updated index.js configuration from React 17 pattern to React 18 pattern (removing console error warning)
Removed package.lock.json since this project relies only on yarn.lock.
Setted up Favicon from generic create-react-app to UCON logo.
Remove unused default features such as setupTests, webVitals and manifest.json.
Reorganized folder structures to a cleaner model, renaming __ tests __ to Tests and nested all examples pages inside Components/Example.
Removed login merge as it used App.css, affecting all others components in the application (should not use App.css), therefore it's necessary to merge the US18/login again.
