tests: update container image for ci and unit test

This patch updates the container image for the CI test workloads:
- `k8s-layered-sc-deployment.yaml`
- `k8s-pod-sc-deployment.yaml`
- `k8s-pod-sc-nobodyupdate-deployment.yaml`
- `k8s-pod-sc-supplementalgroups-deployment.yaml`
- `k8s-policy-deployment.yaml`

Also updates unit tests:
- `test_create_container_security_context`
- `test_create_container_security_context_supplemental_groups`

This fixes tests failing due to an image pull error as the previous image is no longer available in
the container registry.
