Description

The editor's and tech leads are changing for next semester, and since our whilelist isn't dynamic and editable through the admin interface yet we need to update the hardcoded whitelist

How Has This Been Tested?

Shouldn't really need to be tested, the best I guess would be to have the future editors try logging in on our local machine but that's of course too much. In case we have a typo we can always just update it
