urllib.request: Remove deprecated cafile, capath and cadefault parameters in Python 3.13 #105382

In Python 3.12, I removed keyfile and certfile parameters of most stdlib modules in issue #94172, but I forgot to remove cafile and capath of the urllib.request module.

I propose to remove the cafile, capath and cadefault parameters of urllib.request.urlopen() in Python 3.13. These parameters are deprecated since Python 3.6: the context parameter should be used instead. Using cafile and capath is less safe than using the context parameter.
