curl_url_set.md: document HOST handling when URL is parsed

When a full URL is set (parsed), the hostname component is stored URL
decoded (with default zero flags).

While perhaps surprising and inconsistent, the API has done this for
quite some time already and changigtn this now would break existing
behaviour.

Fixes #14942
