adds redirs for older data and removed block paths (#1223)

This PR adds a redirect for the data block page in Terrafrom when you
use the switcher to view an older version of the page. The page did not
exist until 1.12, so we are redirecting to the /data-sources page. This
is PR recreates #1205,
which became bloated with unrelated commits
