minimizer-review: Add reference to 1.8 density factor

 - I cannot find the $1.8/(w+1)$ in either [cite/t:@docks-wabi] or [cite/t:@docks].
+  - It turns out the followup paper [cite/t:@improved-minimizers] states that
+    DOCKS has density factor $1.737$ for $k=w=10$.
 - For which $k$? For $k=1$, this is impossible. For $k>w$, miniception [cite:@miniception] is
   better at $1.67/w$, and in fact, mod-minimizer [cite:@modmini] is even better and
   asymptotically reaches density $1/w$, so this $1.8/(w+1)$ is quite meaningless anyway.
