Cluster autoscaler doesn't respect ignoreDifferences field in gitops application config in RHOCP 4

Issue

• The ignoreDifferences configuration is not being honored for the MachineSet kind.

• The behavior is inconsistent because the same ignoreDifferences configuration works as
  expected for upstream Deployment resources.

• Example configuration that works for Deployment.apps :

  ignoreDifferences:
    - group: apps
      kind: Deployment
      jsonPointers:
        - /spec/replicas
  

  Similar configuration fails for MachineSet.machine.openshift.io :

  ignoreDifferences:
    - group: machine.openshift.io
      kind: MachineSet
      jsonPointers:
        - /spec/replicas
  

• The drift gets continuously detected even when only replica count or auto-managed fields
  change, which should be ignored as per the above configuration.
