Whatsnew bad redirection when changing version

Documentation

There is a bad redirection in the documentation in the whatsnew switch between version 3.11. and 3.12.

How to reproduce :

Link to the whatsnew 3.11 -> https://docs.python.org/3.11/whatsnew/3.11.html

When we switch to 3.12 we arrive in -> https://docs.python.org/3.12/whatsnew/3.11.html

And we see that this is the wrong redirection.

The link should be -> https://docs.python.org/3.12/whatsnew/3.12.html

I remain at your disposal if you need more details

首先，從文件中記載的 3.11 What's New URL 重現切換到 3.12 文件的過程，並檢查用於產生或重新導向 What's New 頁面的 docsbuild-scripts 進入點。完成標準是，從 3.11/3.11.html 切換版本後到達 3.12/3.12.html，而不是繼續保留 3.11 頁面路徑。
