  fix/grass version numbers  (#318)

## fixes

#315 

## what
GRASS version numbers (current, legacy, preview) passed to `/data` folder so it can be a single source of truth and used in multiple places. Using shortcode so it can be used inside markdown files. New sitemap, uses versions from the data. Replaces `static/files/sitemap.xml`.

Only `data/grass.json` needs to be updated in future.
