Error 404 when following Nesting Navigator hyperlink to expo Snack

As the title suggests, when the hyperlink is followed to see the Snack of the nested navigator example instead of the app loading an alert saying "We were unable to load code for file "App.js" (404 - Not Found)" is shown.

Here is the location of the file in the 6.x documentation, the link is also not working in the 7.x documentation either though.
https://github.com/react-navigation/react-navigation.github.io/blob/6f2206e962e08e95dfb57cf494e9c08bc0592e8a/versioned_docs/version-6.x/nesting-navigators.md?plain=1#L6

从链接所指的行开始查看 versioned_docs/version-6.x/nesting-navigators.md，然后检查对应的 7.x 文档，并通过 Nesting Navigator 超链接前往 Expo Snack。更新损坏的目标地址，使嵌套导航器示例能够加载，而不是返回 App.js 404 错误，并验证两个文档链接都能正常工作。
