Dynatrace Operator not respecting namespaceSelector labels

[emdneto]

Describe the bug
The Dynatrace Operator is currently not respecting the namespaceSelector matchLabels configuration. Despite setting specific labels to restrict the operator’s activity to certain namespaces, the Dynatrace OneAgent is being injected into all namespaces. This behavior deviates from the expected functionality, where only namespaces matching the specified labels should be affected by the operator. I'm following this guide: https://docs.dynatrace.com/docs/setup-and-configuration/setup-on-k8s/guides/operation/annotate

To Reproduce
Follow this guide https://docs.dynatrace.com/docs/setup-and-configuration/setup-on-k8s/guides/operation/annotate

Expected behavior
The Dynatrace Operator should only inject the OneAgent into namespaces that have the labels specified in namespaceSelector.matchLabels. Other namespaces without these labels should remain unaffected.

Additional context

• dynatrace-operator:1.2.2

Namespace labels:

ns-xyz                             Active   3d7h     dynakube.internal.dynatrace.com/instance=xyz,kubernetes.io/metadata.name=ns-xyz

Dynakube config:

  oneAgent:
    cloudNativeFullStack:
      autoUpdate: false
      codeModulesImage: public.ecr.aws/dynatrace/dynatrace-codemodules:1.293.182.20240820-160950
      image: public.ecr.aws/dynatrace/dynatrace-oneagent:1.293.182.20240820-160950
      namespaceSelector:
        matchLabels:
          dynatrace: "true"
      tolerations:
      - operator: Exists
      version: 1.293.182

The problem is the namespace doesn't have the label dynatrace: true and even with that pods from that namespace has oneagent injected and the initContainer: install-oneagent
