Adds the dvwa application to the Kubernetes cluster configuration. It includes modifications in the following files:

1. Added dvwa to the resources in manifests/apps/kustomization.yaml.
2. Updated the port number for the dvwa service in manifests/ingress/Ingress.yaml.
3. Created a new Ingress.yaml resource in manifests/ingress/kustomization.yaml.
4. Removed the dependency on azurerm_kubernetes_cluster.kubernetes_cluster in terraform/spoke-k8s_cluster.tf and added a new dependency for azurerm_subnet.spoke_subnet.id.
5. Updated the flux_configuration in terraform/spoke-k8s_cluster.tf to include a new kustomization for the ingress path.

These changes enhance the Kubernetes cluster configuration by adding the dvwa application, ensuring proper networking and resource management within the cluster.
