RFC 8446 recommends using the supported_versions extension to negotiate lower versions as well, so begin by implementing it to negotiate the currently supported versions. Note that pickTLSVersion was incorrectly negotiating the ServerHello version down on the client. If the server had illegally sent a version higher than the ClientHello version, the client would have just downgraded it, hopefully failing later in the handshake. In TestGetConfigForClient, we were hitting the record version check because the server would select TLS 1.1, the handshake would fail on the client which required TLS 1.2, which would then send a TLS 1.0 record header on its fatal alert (not having negotiated a version), while the server would expect a TLS 1.1 header at that point. Now, the client gets to communicate the minimum version through the extension and the handshake fails on the server.
