Keda operator gives error "Webhook not found. Unable to update certificate." after disabling admission webhook

[sinanub18]

Report

We deployed keda 2.13.0 after disabling admission webhook but we are constantly getting below error of unable to update certificate. Is disabling admission webhook disbales cert updation / rotation for metric server and keda-operator as well??

Expected Behavior

Keda operator should able to rotate / update certificate for keda-operator, keda-metricserver and ignore webhook service.

Actual Behavior

keda-operator throwing error "Webhook not found. Unable to update certificate."

Steps to Reproduce the Problem

1. Disable admission webhook
2. Deploy keda operator and keda-metric service with keda managed cert
