worker extensions disabled for python 3.13

From the docs and the code here I can see that the usage of custom worker extensions is not longer supported in python 3.13. All of our function apps are heavily dependent on these extensions, making a transition to python 3.13+ not as straightforward.

Is this feature going to be supported again in the future (in this form or another like middleware or hooks) or should we look for other solutions for our extensions? If the latter is true, is there any migration path that can be followed?

首先查看 issue 中引用的文档和代码，以确认自定义 worker 扩展在 Python 3.13 下的行为。确定是否计划提供未来支持或替代机制，并记录受支持的迁移路径，或说明不存在这样的迁移路径。
