Update getHelpUrls() for reworked mw.org API pages
Community members restructured the mediawiki.org API pages, e.g.
the meta allmessages query submodule is no longer in the catch-all
https://www.mediawiki.org/wiki/API:Meta?oldid=
1408361#allmessages_.2F_am
but its own https://www.mediawiki.org/wiki/API:Allmessages
The links in the generated API help, e.g.
https://www.mediawiki.org/wiki/Special:ApiHelp/query+allmessages, are no
correct. They're not 404s but they don't take you directly to the
relevant page.
This patch set fixes the getHelpUrls() URLs (and does nothing else).
I tested them all.
Thanks RobinHood70!
