[BUG] Instance template's name with dash(-) leads to failure when adding new instance template to Cluster

[leonliao]

Describe the bug
When adding instance template to an existing cluster and the template name has dash(-), kubeblocks reports error:
failed to obtain pod ordinal.

To Reproduce
First, create below Cluster using instance template feature.

apiVersion: apps.kubeblocks.io/v1alpha1
kind: Cluster
metadata:
  labels:
    clusterdefinition.kubeblocks.io/name: mysql
    clusterversion.kubeblocks.io/name: mysql-5.7.44
  name: mysql-demo-leon
spec:
  affinity:
    podAntiAffinity: Preferred
    tenancy: SharedNode
    topologyKeys:
    - kubernetes.io/hostname
  clusterDefinitionRef: mysql
  clusterVersionRef: mysql-5.7.44
  componentSpecs:
  - componentDefRef: mysql
    disableExporter: true
    enabledLogs:
    - error
    - slow
    name: mysql
    replicas: 3
    resources:
      limits:
      requests:
    volumeClaimTemplates:
    - name: data
      spec:
        accessModes:
        - ReadWriteOnce
        resources:
          requests:
            storage: 2Gi
    instances:
    - name: az1-instances
      replicas: 2
      schedulingPolicy:
        nodeSelector:
          my.com/az: az1
    - name: az2-instances
      replicas: 1
      schedulingPolicy:
        nodeSelector:
          my.com/az: az2
  resources:
    cpu: "0"
    memory: "0"
  storage:
    size: "0"
  terminationPolicy: Delete

Then, apply the update with new yml

apiVersion: apps.kubeblocks.io/v1alpha1

    clusterdefinition.kubeblocks.io/name: mysql
    clusterversion.kubeblocks.io/name: mysql-5.7.44

    instances:

      schedulingPolicy:
        nodeSelector:
          my.com/az: az1
    - name: az2-instances
      replicas: 1
      schedulingPolicy:
        nodeSelector:
          my.com/az: az2
    - name: az3-instances
      replicas: 1
      schedulingPolicy:
        nodeSelector:
          my.com/az: az3

  terminationPolicy: Delete
