[aur-requests] [PRQ#34611] Deletion Request for onyx-git

MarsSeed [1] filed a deletion request for onyx-git [2]: Orphaned VCS package for experimental app discontinued in 2018. It was meant to be a messaging app with strong security and privacy, based on the Ethereum Swarm's PSS feature. GitHub repo got archived (made read-ony). Package not needed anymore.
