title: Force lint to check translations on exact languages
body: <p>I get this error:</p>
  
  <blockquote>
    <p>"preferences_default_reminder_labels" is not translated in cs, de, es,
    fr, it, ja, ko, nl, pl, pt, pt-rBR, zh</p>
    
    <p>Issue: Checks for incomplete translations where not all strings are
    translated Id: MissingTranslation</p>
  </blockquote>
  
  <p>But my app needs to be translated in english and russian only. How can I tune lint to check only en,ru translations?</p>
