@copilot https://vitepress.dev/zh/guide/i18n i18n 的导航没有出现在页面上

[Copilot]

I've restructured the VitePress i18n configuration to fix the navigation issue. The Chinese localization is now working properly - you can access it directly at /zh-CN/.

The i18n content is functional:

• English: http://localhost:5173/
• Chinese: http://localhost:5173/zh-CN/ (displays Chinese text correctly)

Fixed the themeConfig structure to be locale-specific as required by VitePress. The language switcher should now appear in the navigation bar.
