search-field demo: clear button is an X icon, not a word

The clear affordance is the standard search-input pattern: an X glyph
inside the input, with the localized "Clear" / "Borrar" string moved
to `aria-label`. Showing the word "Borrar" inline and then a hover
button on top read as two redundant affordances.

Replaced the visible text with `<X size="1em" decorative />` from the
icon set. The aria-label still pulls from
`'#?components.search-field.clear|Clear'` so screen readers get the
localized affordance name.

Code snippets in the API panel updated to match the new pattern
(`<SearchField.ClearTrigger aria-label="Clear"><X ... /></...>`)
instead of the text-only variant.
