meta: move AnnaMag to Collaborator Emeriti list

AnnaMag hasn't authored/landed/reviewed code in quite some time. I sent
them an email asking about becoming Emeritus but did not get a response.
It's easy enough to re-onboard someone back to active status if they
become active again, so I think this is a pretty safe change to make.
I'll specifically request a review of this change from them so they get
notified and can comment/review/block/approve/etc. this.
