[BUG] clickhouse-keeper credential var can't resolve

[loomts]

Describe the bug
credential can't resolve when using other compDef whose name is the prefix of self compDef.name

eg: cmpd-keeper.yaml

apiVersion: apps.kubeblocks.io/v1alpha1
kind: ComponentDefinition
metadata:
  name: clickhouse-keeper
spec:
  vars:
    - name: CLICKHOUSE_ADMIN_PASSWORD
      valueFrom:
        credentialVarRef:
          compDef: clickhouse
          name: admin
          optional: false
          password: Required

will return self compDef.name when resolveReferentComponents

It's by design when compdef name matched by prefix. Try to use the regexp feature introduced in #8094.
