Even though it cannot fall-back to a lower HTTP version automatically. The safer way to upgrade remains via CURLOPT_ALTSVC. CURLOPT_H3 no longer has any bits that do anything and might be removed before we remove the experimental label. Updated the curl tool accordingly to use "--http3". Closes #4197

WARNING: this option is experiemental. Do not use in production.

|
Tells curl to use HTTP version 3 directly to the host and port number used in
|
|
the URL. A normal HTTP/3 transaction will be done to a host and then get
|
|
redirected via Alt-SVc, but this option allows a user to circumvent that when
|
|
you know that the target speaks HTTP/3 on the given host and port.
|
|
|
|
This option will make curl fail if a QUIC connection cannot be established, it
|
|
cannot fall back to a lower HTTP version on its own.
