This commit enhances the "ovn multinode bgp L3 EVPN" multinode test ensuring that OVN advertised logical router NAT and load balancer IPs are indeed accessible from external hosts through an L3 EVPN fabric.
The functionality was already present, NAT/LB IP routes are advertised as regular OVN routes in the VRF that's monitored by FRR, since v25.03, so no code changes are required. The FRR speaker further advertises these as Type-5 EVPN routes for the external BGP speaker to use.
