Commit 73c49a4474 (t: run t5551 tests with both HTTP and HTTP/2, 2022-11-11) added Apache config to enable HTTP/2. However, it only enabled the "h2c" protocol, which allows cleartext HTTP/2 (generally based on an upgrade header during an HTTP/1.1 request). This is what t5559 is generally testing, since by default we don't set up SSL/TLS. However, it should be possible to run t5559 with LIB_HTTPD_SSL set. In that case, Apache will advertise support for HTTP/2 via ALPN during the TLS handshake. But we need to tell it support "h2" (the non-cleartext version) to do so. Without that, then curl does not even try to do the HTTP/1.1 upgrade (presumably because after seeing that we did TLS but didn't get the ALPN indicator, it assumes it would be fruitless).
