Scaleway clusters don't have a VPC yet, so internal load-bal

Error message

Scaleway clusters don't have a VPC yet, so internal load-balancers are not supported at the time

What it means

Configuration guard in the Scaleway API load-balancer builder: the cluster spec requests an internal load balancer for the API, but the Scaleway provider in kOps has no VPC support yet, so only public load balancers can be provisioned.

Solutions

1. Set spec.api.loadBalancer.type to Public for Scaleway clusters
2. Omit the internal load balancer configuration until Scaleway VPC support lands
