The Starter Kits screenshot is the page as it stands today (#126)

* docs(readme): the Starter Kits screenshot is the page as it stands today

The shot predated the current console, so it showed the old shell: a search
bar across the top, and Harnesses and Tasks as separate navigation items.
Retaken from a fresh install of 0.15.2 with one provider connected, which is
where the reader is by that point in the README, so each kit names the harness
and model it will run on rather than reporting that nothing can run it yet.
Same page and same four kits, at 2880x1800 like the other current shots.
