Fixed SSL wrap_socket compatibility for Python 3.13

[Santosh-Baliarsingh]

Summary

Python 3.13 removed ssl.wrap_socket, causing AttributeError when running h2csmuggler.

Fix

Replaced:

retSock = ssl.wrap_socket(sock, ssl_version=ssl.PROTOCOL_TLS)

with

context = ssl.SSLContext(ssl.PROTOCOL_TLS)
retSock = context.wrap_socket(sock, server_hostname=proxy_url.hostname)
