[br-restore] when cluster name not exists, can we give specific tips？

[jinyingsunny]

when execute restore , the status is null，actual because cluster name is wrong，it should be nebula-ent-sc, but i set as nebula

restore.yaml:

apiVersion: apps.nebula-graph.io/v1alpha1
kind: NebulaRestore
metadata:
  name: restore1
  namespace: nebula-ent-sc
spec:
  br:
    clusterName: nebula
    backupName: "BACKUP_2023_08_07_07_52_28"
    concurrency: 5
    s3:
      region: "us-west-2"
      bucket: "test-qa"
      endpoint: "http://192.168.8.202:32000"
      secretName: "aws-s3-secret"

from the follow logs ,i can not realize the problem is cluster name is wrong, can we give specific tips？
