Attempt HTTP 2 requests. libcurl will fall back to HTTP 1.1 if HTTP 2 can't be

The alias \fICURL_HTTP_VERSION_2\fI was added in 7.43.0 to better reflect the
actual protocol name.

Attempt HTTP 2 over TLS (HTTPS) only. libcurl will fall back to HTTP 1.1 if
HTTP 2 can't be negotiated with the HTTPS server. For clear text HTTP servers,
libcurl will use 1.1. (Added in 7.47.0)
