[BUG] Could not set nodeAffinity in dataset

[weixiao-huang]

What is your environment(Kubernetes version, Fluid version, etc.)

• K8s: 1.22.12
• fluid: v0.8.4

Describe the bug
create a dataset like

apiVersion: data.fluid.io/v1alpha1
kind: Dataset
metadata:
  name: test
spec:
  mounts:
  - mountPoint: local:///data/shared/sharefs-01/brain/test-sharefs
    name: test
  nodeAffinity:
    required:
      nodeSelectorTerms:
      - matchExpressions:
        - key: my-test
          operator: DoesNotExist

and create an alluxioruntime due to this dataset, but we see logs in alluxioruntime-controller

Error: unable to build kubernetes objects from release manifest: error validating "": error validating data: ValidationError(StatefulSet.spec.template.spec.affinity.nodeAffinity): unknown field "RequiredDuringSchedulingIgnoredDuringExecution" in io.k8s.api.core.v1.NodeAffinity

2023-03-22T10:46:02.517+0800    ERROR   helm    helm/utils.go:59        failed to execute       {"args": "install -f /tmp/test-alluxio-values.yaml1003339927 --namespace brain-pro01 test /charts/alluxio", "error": "exit status 1"}

By checking the values.yaml, we can see bug below

master:
  affinity:
    nodeAffinity:
      RequiredDuringSchedulingIgnoredDuringExecution:
        NodeSelectorTerms:
        - MatchExpressions:
          - Key: my-test
            Operator: DoesNotExist
            Values: null

the RequiredDuringSchedulingIgnoredDuringExecution should be requiredDuringSchedulingIgnoredDuringExecution

What you expect to happen:
Create alluxioruntime successfully
