The languages alert is misleading when there are no languages and the user has JS disabled.
This change adds a class to the alert if there are 0 languages, and then adds "display: none" to the alert if the client-nojs class is present. This is the same approach being used for the language switcher button.

It should be possible to style the language alert without impacting the opt in
action.
