hhfab vlab setup-peerings 1+2:gw: denied the request: at least one IP block must be specified in peering expose

While running the VLAB demo steps I hit:

After redeploying VLAB:

The issue seems to arise if we first setup VPC Peering first via kubectl fabric vpc peer --vpc vpc-1 --vpc vpc-2 and later via ./hhfab-25.05 vlab setup-peerings 1+2:gw
