Add TinyTapeout carrier board colors / pictures to runs page

[mithro]

The page @ https://tinytapeout.com/runs/ is kind of bland.

It would be awesome to have each run show the board like what I have done in the spreadsheet at https://docs.google.com/spreadsheets/d/1xD_uemuQcpUnXRY4twOrfFzF0urJLVWMdqAnrOJLetM/edit?gid=1439118929#gid=1439118929

Nice sheet!

Agree that the runs page could use some more visuals.
