4.0r2 release notes referencing sarge

["Ryan Finnie" <ryan@finnie.org>]

Not a big deal, but on the release notes page for upcoming 4.0r2[0],
there are a few references to the last sarge release.

"An up-to-date version is at http://release.debian.org/stable/3.1/4.0r2/.";

"We are preparing the next revision of the current stable Debian
distribution (sarge)"

"The next revision of stable should therefore be released at the mid
of February or 48h before the release of Etch, whatever comes first."
