[PRQ#64772] Deletion Request for akula-git

MarsSeed [1] filed a deletion request for akula-git [2]: Obsolete, broken, but no longer useful. Reportedly fails to build in clean env (as per @xrchz's comment from 2022-08-06). Project was sunsetted and archived in Dec 2022 [a] in favor of other Rust-based Ethereum implementation(s).
