    Resolve kubeadm alpha Check in kube-cert-rotation Script

    The 'kube-cert-rotation' script evaluates the status
    of the 'kubeadm' command to determine if it is in
    alpha mode. This modification addresses an issue with
    the check, ensuring it conforms to the correct usage.
    After kubernetes v1.21 the 'kubeadm alpha' has been
    deprecated.

    TEST PLAN:

    PASS: Deploy the DC (with dc-libvirt) and verify
          that alarm 250.003 is not triggered.
