Bug fixes
:   - Before this update, the `default` scaling strategy for scaled jobs was missing. With this fix, the `default` strategy has been added back to the `scaledjobs` custom resource. As a result, you can select the default strategy with scaled jobs. ([OCPBUGS-98657](https://redhat.atlassian.net/browse/OCPBUGS-98657))

- Before this update, the `installAdmissionWebhooks` function was incorrectly using `Operator.Volumes` and `Operator.VolumeMounts` parameters instead of the `AdmissionWebhooks.Volumes` and `AdmissionWebhooks.VolumeMounts` parameters. This caused user-configured volumes for admission webhooks to not be applied correctly, because the Operator’s volumes were used instead. With the fix, the Custom Metrics Autoscaler Operator correctly configures admission webhooks, ensuring the proper deployment of user-defined volumes and volume mounts.
