This was done in the library, but it was breaking WireGuard operation. The official WireGuard app doesn't route DNS through the VPN unless the server is explicitly added to AllowedIPs.
Therefore, move the explicit DNS routes to the OpenVPN implementation (like it was done in TunnelKit), and maybe remove the code later because such routes are probably redundant.
