Adds mediawiki.conf, the eleventh change: on MediaWiki's paths, the fields
that carry a search, a title, a name, a file name or an address skip the
four rules that read them as commands or system files, and the wikitext
fields skip the rules that refused saving a page. /index.php counts as
MediaWiki's only with a title in its query, since WordPress serves it too.
The recorded requests from MediaWiki 1.46.2 pass at the defaults and while
bodies are read. The app tests share the check of recorded requests and the
list of hard values.
