Forces curl to use TLS version 1.3 or later when connecting to a remote TLS
server.
Note that TLS 1.3 is only supported by a subset of TLS backends. At the time
of this writing, they are BoringSSL, NSS, and Secure Transport (on iOS 11 or
later, and macOS 10.13 or later).
If the connection is done without TLS, this option has no effect. This
includes QUIC-using (HTTP/3) transfers.
Note that TLS 1.3 is not supported by all TLS backends.
