Publish the wiki in English, Danish and Bahasa Malaysia

Add a Danish (.da) and a Bahasa Malaysia (.ms) page for each of the five
wiki pages, a language bar on every page and a three-language sidebar, as in
the wiki of TirSystem/github-action. Each translation records the sha256 of
the English page it follows and names English as authoritative.
