Translator: targetLanguage property

The targetLanguage read-only property of the Translator interface returns the language that the input text will be translated into.

A Translator instance's targetLanguage is set when creating it via a create() call.

const translator = await Translator.create({
  sourceLanguage: "en",
  targetLanguage: "ja",
});

// Logs "ja"
console.log(translator.targetLanguage);
