arangodb currently cannot build on Apple Silicon (https://github.com/Homebrew/homebrew-core/pull/68561), Apple's new ARM processor for macOS, because only go1.16 supports this platform (darwin-arm64).

@fxcoudert should we just check go-1.16 possibility on our side or general ARM compatibility is required by Homebrew now? Can we mark somehow that we don't support ARM in our formula at the moment? If yes, can you please tell how to do it properly.

ArangoDB now can be built on darwin-arm64. Starter uses go1.19
