release-notes: build date on PDF's first page

[Simon Paillard <simon.paillard@resel.enst-bretagne.fr>]

Hi,

As spotted by people on #debian-release, pubdate was set at 2009-02-01
(can be seen on 2nd page on PDF or at the beginning of HTML version).
*That* is fixed.

But the date displayed on the first page of every PDF is the one of the
build, see :
http://www.debian.org/releases/lenny/i386/release-notes.en.pdf

I guess dblatex doesn't consider pubdate as Latex \date, would adding
<date>2009-02-14</date> solve it (no dblatex installed) ?
