unknown extensions type "oidc" for "oidc" (valid values: [pprof zpages memory_ballast health_check])

Currently seems it is not possible to configure the extension oidc.

I've installed the operator using helmfile with:

- name: open-telemetry
  namespace: opentelemetry-operator-system
  chart: open-telemetry/opentelemetry-operator
  set:
    - name: admissionWebhooks.certManager.enabled
      value: true
    - name: version
      value: 0.9.2

The operator is install correctly:

❯ kubectl get pods -n opentelemetry-operator-system 
NAME                                                         READY   STATUS             RESTARTS        AGE

But when I try to add a collector the log shos the next message:

❯ kubectl logs -n opentelemetry-operator-system collector-collector-cfdd99668-74qm5 
Error: failed to get config: cannot unmarshal the configuration: unknown extensions type "oidc" for "oidc" (valid values: [pprof zpages memory_ballast health_check])

The collector manifest used is the next(Following the Oficial documentation:
