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.
Gitea stores a page whose name has a hyphen under an escaped address
(Getting-started.-), which the shared publish workflow does not match, so
the second run tried to create the page again and got HTTP 400. Use
GettingStarted and SshAndTokens, as the wiki of TirSystem/github-action
does.
