Endpoint Querier RuleIndex not showing expected index

[qiyueyao]

Describe the bug
The current Endpoint Querier RuleIndex shows the index of the rule among all matched rules in the policy for
this endpoint, which is not super helpful for users to find the rule from the original policy.

To Reproduce
Apply

  namespace: default

              matchLabels:

        name: AllowFromFoo
      - action: Allow
        from:

              matchLabels:
                app: bar
        name: AllowFromBar
