fix: respect the anonymize value from CR during initialization

[arbreezy]

Closes #306

📑 Description

Small PR to address a behaviour with kubebuilder markers and booleans. During initialisation of K8sGPT, the operator will attempt to add a finaliser and the K8s api server will not be able to distinguish if that's a default value or something that is been explicitly set from the CR thus setting the default which is true
