As an event organizer, I want the Event Organizer right to be managed by admins, so that the right is managed in a way that is more aligned with general wiki practices and so that the right can be granted or revoked with greater efficiency.
**Background:** The campaignevents-beta-tester right is how organizers can access organizer tools (such as enabling Event Registration on an event page, managing a participant list, emailing participants, collecting data on participants, etc). It has been managed by stewards in the past, but we are changing the process so it is managed by wiki admins. This change allows admins to have direct control over who has the Event Organizer right on the wikis, and it will improve the efficiency of granting/revoking the right, since more people can review requests. Since the CampaignEvents extension is currently only enabled on Meta-Wiki, we have started with consultation with Meta-Wiki admins (see [[ https://meta.wikimedia.org/wiki/Meta:Requests_for_help_from_a_sysop_or_bureaucrat#Transitioning_Event_Organizer_Rights_Management_to_Meta-Admins | discussion ]]).
**Acceptance Criteria:**
* Change the name of the right from "campaignevents-beta-tester" to "Event Organizer"
* Change the management of the right, so that wiki admins can grant or revoke the right for any user
** Note: This will start with admins on Meta-Wiki, since the CampaignEvents extension is only enabled on that wiki, but this rule will be the default for other wikis, though perhaps this may be something they configure differently (to be discussed)
