Fixing the panicRPSM parameter in autoscaler

[Nalin28]

The value of panicRPSM was set as observedStableValue, but it should have been observedPanicValue.

Fixes #12909

Proposed Changes

Changed panicRPSM.M(observedStableValue) to panicRPSM.M(observedPanicValue) in autoscaler.

Release Note

The value of panicRPSM was set as observedStableValue, but it should have been observedPanicValue as part of the metric collection.

Hi @Nalin28. Thanks for your PR.

I'm waiting for a knative member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

If needed, /assign to me as well for approval, but I'm hoping to get Nader that power-up soon. 😁
