fix(Traefik Proxy): allowEmptyServices not disabled when set to false

[MaximilianMeister]

What does this PR do?

Explicitly disallow empty services when values are set this way:

providers:
  kubernetesCRD:
    allowEmptyServices: false
  kubernetesIngress:
    allowEmptyServices: false

Motivation

The bug is if we don't explicitly set the cmdline flags to false, they will always default to true:

• https://github.com/traefik/traefik/blob/v3.2/pkg/provider/kubernetes/ingress/kubernetes.go#L52
• https://github.com/traefik/traefik/blob/v3.2/pkg/provider/kubernetes/crd/kubernetes.go#L62

More

• Yes, I updated the tests accordingly
• Yes, I updated the schema accordingly
• Yes, I ran make test and all the tests passed
