i18n support for notification-center component

It is now possible to translate the notification center UI elements by passing a translation object or a premade translation. More info can be found on the documentation page.

Custom object implementation:

<NovuProvider i18n={{
  // Make sure that the following is a proper 2 letter language code,
  // since this is used by moment.js in order to calculate the relative time for each notification
  lang: "de",
  
  translations: {
    poweredBy: "unterstützt von",
    markAllAsRead: "Alles als gelesen markieren",
    notifications: "Benachrichtigungen",
  },
}}>
</NovuProvider>

Premade languages created by the community:

<NovuProvider i18n={'en'}>
</NovuProvider>
