showcase: rename SVG to showcase-rank-history.svg, link at top of gemtext

- Rename output file from rank-history.svg to showcase-rank-history.svg so
  it sits alongside the showcase.gmi.tpl with a consistent name prefix.
- Move the rank-history link from below the intro paragraph to immediately
  after the date line, making it the first thing a reader sees.
