Webhook testdata doesn't build over 1 year ago

AI Summary: The issue is that the webhook testdata in the Kubernetes controller-tools project fails to build because the `CronJob` struct is missing the `DeepCopyObject` method, which is required by the `ctrl.NewWebhookManagedBy` function and the webhook defaulter and validator interfaces. The solution involves generating the `DeepCopy` methods for the `CronJob` struct, likely using the `deepcopy-gen` tool.

Complexity: 3/5
