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?

Start by reviewing the documentation and code referenced in the issue to confirm how custom worker extensions behave under Python 3.13. Determine whether future support or an alternative mechanism is intended, and document a supported migration path or the absence of one.
