TLSv1.3 should be among possible return values of ssl.SSLSocket.version

Documentation

Currently the https://docs.python.org/3.15/library/ssl.html#ssl.SSLSocket.version doc states:

Return the actual SSL protocol version negotiated by the connection as a string, or None if no secure connection is established. As of this writing, possible return values include "SSLv2", "SSLv3", "TLSv1", "TLSv1.1" and "TLSv1.2". Recent OpenSSL versions may define more return values.

I got TLSv1.3:

>>> import socket
... import ssl
... 
... hostname = 'lebihan.pl'
... context = ssl.create_default_context()
... 
... with socket.create_connection((hostname, 443)) as sock:
...     with context.wrap_socket(sock, server_hostname=hostname) as ssock:
...         print(ssock.version())
...         
TLSv1.3

从 issue 中链接的 ssl.SSLSocket.version 文档部分开始，将当前可能的返回值列表与报告的 TLSv1.3 输出进行核对。完成标准是文档准确涵盖 TLSv1.3；gh-154785 已经与这项工作关联。
