Lobby websocket - fix disconnect - increase ping frequency (#12806)

Lobby was upgraded recently to be on a newer version of the
server platform. Seemingly the websocket timeout has dropped
to 30 seconds. The previous keep-alive of 45 seconds was
not enough.

Changing the value to 10 seconds allows for 3 failed tries before
a disconnect.
