fixed api end point for match making

[PramanandaSarkar]

in the backend/routes/match.js
modify the routes and add functionality

// Add a player to the queue
router.post("/join-queue", joinQueue);
// Remove a player from the queue
router.post("/leave-queue", leaveQueue);
// make all possible match in queue
router.get("/make-match", makeMatch);
// find match by id
router.post("/get-match", getMatch);
