Skeleton for Translation

[IsmailM]

Further to #358 / #265

This is pretty easy:

1. First update config:

i18n.init({
  react: {
     wait: true,
     useSuspense: false,
  }
})

2. Next use ready from the useTranslation() hook:

  const { t, ready } = useTranslation();

  /// render skeleton as long as ready === false
