[emacs-w3m:13872] Need to update w3m-search-engine-alist for Wikipedia?

Hello,

seems the urls for searching Wikipedia changed?  Since a couple of days
using the urls from "de.wikipedia" and "en.wikipedia" (I guess
"ja.wikipedia" as well) in `w3m-search-engine-alist' gives me a non
responding server.  Wikipedia is not down, searching with the web
interface works.

This works for me:

#+begin_src emacs-lisp
(setf (alist-get "de.wikipedia" w3m-search-engine-alist nil nil #'equal)
      (list "https://de.wikipedia.org/w/index.php?title=Spezial:Suche&search=%s"))
#+end_src

(got that with Firefox by clicking in the search field and selecting
"add keyword for search" and inspecting the created bookmark; dunno
about the uft-8 flag)

So I guess the URLs must be updated?

TIA,

Michael.
