If the changes in this PR are not 100% Ruby2 compatible then this PR will be deleted (without merge) and the Ruby3 apps will just be built with ruby-engine on branch fix/ruby3 instead of master

With the changes the deployed, the error has now changed to:

[error] unhandled exception: wrong number of arguments (given 9, expected 0; required keywords: status, callback, on_thread) (performing next tick callback)
/home/aca-apps/ruby-engine/lib/orchestrator/status.rb:53:in `subscribe'
/home/aca-apps/ruby-engine/lib/orchestrator/websocket_manager.rb:304:in `block in try_bind'

So the syntax is still not correct
