Update xray please #78
Description
Please update xray. The marzban-node update-core command installs another xray of a different version without replacing the old one, resulting in two xray versions running simultaneously on the node.
It would be nice to have the node version be the same as the one on the dashboard. That is, if the dashboard has the latest version, the node automatically gets the latest version. And if the xray on the dashboard is updated, the node gets updated as well. So, there should be synchronization. I hope I explained it clearly.
