refactor(App.tsx): Update component rendering and variable names

- Replace 'createSignal' with 'For' for iterating over components.
- Rename 'children' to 'examples' for better semantic meaning.
- Uncomment and adjust 'menus' as it's not currently used.
- Wrap the component returns in a parent <div> element.
