gh-99352: Export HTTPSHandler from urllib.request

[arhadthedev]

Fixes a builbot failure due to gh-99353 importing previously unexported urllib.request.HTTPSHandler into a test:

test test_urllib2 crashed -- Traceback (most recent call last):

AttributeError: module 'urllib.request' has no attribute 'HTTPSHandler'. Did you mean: 'HTTPHandler'?

I've met this error in #19474 (comment).

• Issue: urllib.request.urlopen() no longer respects the http.client.HTTPConnection.debuglevel flag #99352
