[help needed] Upgrade to Onlyoffice version to 8.0.0 ( stuck at 7.2.X )

I've been trying to update to last Onlyoffice version (7.4.1 and more recently to 8.0.0) but since 7.3.0, they changed a vendor sockjs to socket.io and it drops an error while trying to load a socket.io component on loading a document. I have been digging a bit and this thread might help resolve this for good but unfortunately I'm still not php friendly enough to get to understand how to fix this for now :c

Any PR/help on this would be really appreciated!
