Events for ScheduleEvent updates.


These events require the SCHEDULED_EVENTS intent and CacheFlag.SCHEDULED_EVENTS to be enabled.
createDefault(String) and createLight(String) disable this by default!

Discord does not specifically tell us about the updates, but merely tells us the ScheduledEvent was updated and gives us the updated ScheduledEvent object. In order to fire specific events we need to have the old ScheduledEvent cached to compare against.
