Fix story README metadata and a broken cross-story link

- Add title/description/date frontmatter to four stories that had none, and
  drop their leading H1. Without frontmatter, datahub.io derived a title from
  the slug and then rendered the H1 too, showing the title twice.
- Fix a `descritption:` typo in the carbon-footprint story so its description
  metadata is no longer silently dropped.
- Replace a relative `../the-15-most-carded-matches.../` link in the dirtiest
  story with its absolute datahub.io URL, which resolves on the published site.

 Some World Cup matches stop being football. The referee runs out of patience, the cards
 pile up, and a quarter-final turns into a brawl with a scoreline attached.
