Remove untranslated Chinese languages from Tails Greeter

See screenshot in attachment.

These are not languages that people use and even their name is not translated in Tails. They take up more space that groups of translated language names (who are collapsed under a single name, like “Español”) and are confusing because they appear before the Chinese that works (and that has it’s name translated) at the very bottom of the list.
