Subject: [PATCH] Tighten return type of OpenSSL Connection.get_protocol_name()
 (#5972)

The method always returns a str. See implementation at:

https://github.com/pyca/pyopenssl/blob/30e82d4ba5e3817a77e212540477da701460e988/src/OpenSSL/SSL.py#L2420-L2430

If version were ever None, it would raise an exception on the .decode()
line.
