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，从文档中记录的 3.11 What's New URL 复现切换到 3.12 文档的过程，并检查用于生成或重定向 What's New 页面 的 docsbuild-scripts 入口点。完成标准是，从 3.11/3.11.html 切换版本后到达 3.12/3.12.html，而不是继续保留 3.11 页面路径。
