fix: spurious HTMX console warnings from checkbox-list default hx-include

The checkbox-list partial defaulted hx-include to 'this, #website-url-fieldset',
but #website-url-fieldset only exists when `Site web` is checked in the
format list.  Every language checkbox click triggered a no-match warning
and a cascade triggering the known HTMX internal-data crash.
