When I use the persistent volume claim of kubernetes plugin and set read-only, readonly is now set under volumes, which should be under volumemounts. This will cause the actually mounted directory to still be written to or even deleted, which is dangerous

-----------------------------------
expect：
-----------------------------------
...
    volumeMounts:
    - mountPath: "/tools"
      name: "volume-1"
      readOnly: true
...
  volumes:
  - name: "volume-1"
    persistentVolumeClaim:
      claimName: "jenkins-tools-pvc"
...

-----------------------------------
actual (This is wrong)：
-----------------------------------
...
    volumeMounts:
    - mountPath: "/tools"
      name: "volume-1"
      readOnly: false
...
  volumes:
  - name: "volume-1"
    persistentVolumeClaim:
      claimName: "jenkins-tools-pvc"
      readOnly: true
...
