bug#63497: [PATCH] Remove obsolete information on archiving mail from Gnus manual

[Jens Schmidt via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

Hi,

my first test patch to practice things, pls comment if its format is not 
what you expect.  I hope Thunderbird does not mess up the format.  FSF 
copyright assignment is in process, but probably not yet completed.

Regardless of this being a test patch, it fixes a real but minor doc 
issue in the Gnus manual:  In 2012 Lars committed a change that removed 
the previous "external marks" feature  from various backends 
(89b163db286d79b43fb5c9927fc622bbf7d2ef1a).

The Gnus manual still references these external marks in section 
"Archiving Mails", I guess that reference just got overlooked.  But 
without external marks, archiving mails in Gnus is rather difficult (to 
my knowledge), at least for the nnml backend.  So I decided to rather 
remove that section entirely.

Thanks

Jens
