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

從連結所指向的行開始查看 versioned_docs/version-6.x/nesting-navigators.md，接著檢查對應的 7.x 文件，並透過 Nesting Navigator 超連結前往 Expo Snack。更新失效的目的地，讓巢狀導覽器範例能夠載入，而不是回傳 App.js 404 錯誤，並確認兩個文件連結都能正常運作。
