Downloads the core translation and sets it as the site language. The default value installs German, and de_DE_formal provides the formal German variant. Plugin and theme translations follow with wp language plugin install --all de_DE and wp language theme install --all de_DE.

Note: The language also sets the lang attribute in the HTML, which is relevant for search engines.
