Fix language prefix handling in example navigation links

- Update getExampleLink function in examples.tsx to maintain language prefix when navigating to example details
- Update handleBackToHome function in example-detail.tsx to maintain language prefix when returning to examples page
- Ensure all example-related navigation preserves the current language context

This fixes the issue where navigation links were not preserving the language prefix,
causing incorrect URL paths when switching between pages in different languages.
