A <link rel> attribute is a space-separated token list, but kage matched
the whole string against its set of downloadable rels. So a tag like
<link rel="preload stylesheet" href="/assets/style.css"> matched neither
"preload" nor "stylesheet" and its stylesheet was left on the live web,
absolute and undownloaded.
VitePress ships exactly this form, and it is the only stylesheet on the
page, so a cloned Vue docs site (and any other VitePress site) rendered
completely unstyled offline.
Tokenize the rel and match if any single token is a known asset rel, the
way the HTML spec reads it. This also subsumes the old combined
"shortcut icon" entry, since the "icon" token alone now matches.
