The OutputPage::parse() method emits untidy output and is often used
with the wrong user interface/content language selection. Replace
with Message::parseAsBlock() which was tidied in
I0f417f75a49dfea873e9a2f44d81796a48b9f428.

The replacement OutputPage::addWikiMsg() method is ancient, and so
no bump to the minimum required MW version is needed.

If we're going to call `OutputPage::addWikiText` to parse the message,
we don't need to pre-expand `{{...}}` markup using `Message::text()`
before passing it to the parser; `Message::plain()` works fine. This
makes these callsites consistent with how `OutputPage::addWikiMsg()`
inserts messages.
