doc: Avoid invalid 'match' pattern in 'syntax-highlighted-html'.
This is a followup to da9deba13d551e316f5a99a614834efa27ddc7d1.
Last-minute modification of the 'match' pattern would lead to an error:
"multiple ellipsis patterns not allowed at same level"
* doc/build.scm (syntax-highlighted-html)[build](collect-anchors):
Add 'worthy-entry?' procedure and use it instead of the unsupported
pattern for ('dt ...).
