[test:networking] Update tests for OpenSSL 3.2

[bashonly]

OpenSSL 3.2 slightly tweaked its error messages which was causing some of our networking tests to fail:

FAILED test/test_networking.py::TestHTTPRequestHandler::test_ssl_error[Urllib] - AssertionError: Regex pattern did not match.
FAILED test/test_networking.py::TestHTTPRequestHandler::test_ssl_error[Requests] - AssertionError: Regex pattern did not match.
FAILED test/test_websockets.py::TestWebsSocketRequestHandlerConformance::test_ssl_error[Websockets] - AssertionError: Regex pattern did not match.

The new error message is:

[SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] ssl/tls alert handshake failure

vs. the old:

[SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure
