Mismatch socket-io version between frontend and backend cause connection issue between client and server

[Jlu18]

Currently the frontend has "socket.io-client" running on version ^4.4.1, but the backend socket.io server is running with version ^2.3.0. This mismatch version between client and server cause the client not able to communicate to the server via socket (Go to production and open network tab on inspector, notice how socket.io keep trying to connecting and disconnecting from the server ).

All the feature using socket.io are currently unavailable (ie. notifying devices when scene is updated).

To fix this, we have to bump the version of socket.io to match with the client. But to do so, migration from 2.x to 4.x must be done. migration guide
