Let people play with bots in Conquest mode without internet connection.

@AristarhUcolov2 My biggest concern as we approach launch is the server performance. It seems like EA games across the board are not performing well online, not to mention hackers. Apex and TitanFall are having serious hacker and server problems. BF4 lags and skips for me on occasion. If this happens in BF2042, then yeah, I'm going to want a way to play this offline to at least feel like I'm getting my money's worth.
