fix: support new "most popular 100" & "bottom 100" HTML

The previous version had all 100 movies rendered into the HTML.  The new
version has only the top 25 rendered into HTML, but the whole list has
been made available as LD+JSON data.
Since we can easily support both, we don't (yet) remove the old parser.
