fix(notifications): Notifier::prepare() threw \InvalidArgumentExcepti…

…on which is deprecated

Possible since Nextcloud 30, and that's the minimum on main, so should be okay?

OCA\Calendar\Notification\Notifier::prepare() threw \InvalidArgumentException which is deprecated. Throw \OCP\Notification\UnknownNotificationException when the notification is not known to your notifier and otherwise handle all \InvalidArgumentException yourself
