fix(openshift): add missing vLLM model PVCs to deployment script

Add PersistentVolumeClaim creation for vllm-model-a-cache and vllm-model-b-cache to ensure all required storage is provisioned during automated deployment. This fixes pods being stuck in Pending state when running the deploy-to-openshift.sh script.

Changes:
- Add vllm-model-a-cache PVC (10Gi)
- Add vllm-model-b-cache PVC (10Gi)
- Ensures full automation without manual PVC creation
