doc: Replace unreproducible date->string computation.

The date->string computation is unreproducible. A slightly different
version of the documentation is built each time. Also, the output of
date->string is locale dependent, and does not render correctly in all
locales.

* doc/user/start.skb (Dynamic Documents)[Simple Computations]: Replace
unreproducible date->string computation with a square root
computation.
