bug#73426: [EPA Manual] HTML error suppresses a Lisp example

[Thérèse Godefroy]

Hello,

While checking a few manuals to improve the main stylesheet [0], I
noticed a bug in the EasyPG Assistant manual: the first Lisp example is
blank! After fixing the markup, this example is displayed normally
(compare the attached screenshots).

The MH-E manual has the same error. I didn't check the other Emacs
manuals.

emacs-manual.patch (attached) fixes the markup.

[ By the way, the MH-E manual says it was last updated on 2016-04-29,
but the copyright line is:
Copyright © 1995, 2001—2003, 2005—2024 Free Software Foundation, Inc. ]

Best,
Thérèse

Suggestions to improve this stylesheet are appreciated.
