Feature Request: CroJobs

### Feature request

Requesting support for CronJobs. Currently image substitution in CronJobs does not work.

```yml
deploy:
name: Deploy
needs: [ build, publish ]
runs-on: ubuntu-latest
steps:
- name: Set the Kubernetes context
uses: azure/k8s-set-context@v2
with:
method: service-account
k8s-url: https://my-kube-domain
k8s-secret: ${{ secrets.KUBERNETES_SECRET }}

- name: Checkout source code
uses: actions/checkout@v3

- name: Deploy to the Kubernetes cluster
uses: azure/k8s-deploy@v1
with:
namespace: default
manifests: |
kube/cronjob.yml
images: |
asia-south1-docker.pkg.dev/project/repo/image:${{ github.sha }}
```

Expected: CronJob is updated with the new image as per `${{ github.sha }}`
Actual: Image name that is hardcoded, gets updated
