Omit edition numbers and dates in manuals

These seem to cause more confusion than they cure; e.g.,
https://shop.fsf.org/books/gnu-emacs-manual-18th-edition-v-261
currently advertises "18th edition" even as it points to
https://www.gnu.org/software/emacs/manual/pdf/emacs.pdf
which says "Seventeenth Edition".  It is simpler and less
confusing to stick to one version number like "26.3".  If we
need a separate edition number for each printed manual for
some reason (marketing?) we can put “@ifset printed-edition”
around anything specific to the printed editions.
(as opposed to online PDF copies).
* doc/emacs/emacs.texi (EDITION):
* doc/lispintro/emacs-lisp-intro.texi (edition-number, update-date):
* doc/lispref/elisp.texi (VERSION, DATE):
Remove, and remove uses.

-@c The edition number appears in more than one place in this file
-@c I don't really know what it means...
-@c For example, it has said "Sixteenth" since sometime in the Emacs 22
-@c series, all through 23, and into 24.  So it is not very useful IMO,
-@c and offers nothing that EMACSVER does not.  I guess it relates
-@c mainly to the published book sold by the FSF.  Hence no longer
-@c bother including it except iftex.  Really, I think it should not be
-@c here at all (since anyone can make a pdf version), but should just
-@c be something added by the FSF during the publishing process.
-@c Also, the lispref uses a float (3.0), whereas this uses an ordinal,
-@c so the format is not even consistent.
