bug#5807: artist.el doc string bugfix

[Tomas Abrahamsson]

Hi,

  regarding the emacs/lisp/textmodes/artist.el file: it was brought to
my attention, by Alex Schröder <kensanata@gmail.com>, that there's a
typo in the doc string for the `artist-mode' function.

Below is a simple patch for fixing it and also a ChangeLog entry (for
lisp/ChangeLog, which is where I assume such an entry would go).

BRs
Tomas

        * lisp/textmodes/artist.el (artist-mode): Fix typo in docstring.
