text: Title: Update experiment instance status failed: the object has been modified
  Body: /kind bug
  
  **What steps did you take and what happened:**
  
  I got error when update experiment status in experiment controller.
  ```
  {"level":"info","ts":"2024-03-04T01:39:38Z","logger":"experiment-controller","msg":"Update experiment instance status failed, reconciler requeued","Experiment":{"name":"a10702550312415232282375","namespace":"heros-user"},"err":"Operation cannot be fulfilled on experiments.kubeflow.org \"a10702550312415232282375\": the object has been modified; please apply your changes to the latest version and try again"}
  ```
  
  **What did you expect to happen:**
  
  The code of experiment status update as follow. It's not supposed to raise error cause it only updates status even if experiment object is modified. I'm not sure my understanding is ok.
  https://github.com/kubeflow/katib/blob/master/pkg/controller.v1beta1/experiment/experiment_controller.go#L237
  ```go
  	if !equality.Semantic.DeepEqual(original.Status, instance.Status) {
  		// assuming that only status change
  		err = r.updateStatusHandler(instance)
  		if err != nil {
  			logger.Info("Update experiment instance status failed, reconciler requeued", "err", err)
  			return reconcile.Result{
  				Requeue: true,
  			}, nil
  		}
  	}
  ```
  
  **Environment:**
  
  - Katib version: v0.16
  - Kubernetes version: v1.25.13
  - OS: Linux 5.15.47-1.el7.x86_64 x86_64
