## PR-Codex overview
This PR introduces new `Chain` components to enhance the user interface for blockchain applications, allowing for the display of chain icons and names. It includes new pages and components that integrate these features into the existing playground web application.

### Detailed summary
- Added a new `Chain` entry in `navLinks.ts`.
- Created a new page in `page.tsx` for `Chain` components with metadata.
- Integrated `ThirdwebProvider`, `APIHeader`, `ChainIconBasic`, and `ChainNameBasic` components.
- Implemented `ChainIconBasic` and `ChainNameBasic` components in `chain-examples.tsx` to showcase chain icons and names.
