[bug#69432] [PATCH guix-artwork v2 2/3] website: Use Fira Sans for section headings only.

["Ludovic Courtès" <ludo@gnu.org>]

With commit b7ccc5cb1b4ec936c00dbd98376c5d2677e60a63, Fira Sans was used
for the body of sections, not just section headings.  This is what
<https://www.gnu.org/software/gnulib/manual.css> prescribes but it’s not
what was intended.

* website/static/base/css/manual.css: Add rule.
