    [MINOR][DOCS] Update running-on-kubernetes.md
    
    ### What changes were proposed in this pull request?
    
    Fix executor container name typo. `executor` should be `spark-kubernetes-executor`.
    
    ### Why are the changes needed?
    
    The Executor pod container name the users actually get from their Kubernetes clusters is different from that described in the documentation.
    
    For example, below is what a user get from an executor pod.
    ```
    Containers:
      spark-kubernetes-executor:
        Container ID:  docker://aaaabbbbccccddddeeeeffff
        Image:         <imagename>
        Image ID:      docker-pullable://0000.dkr.ecr.us-east-0.amazonaws.com/spark
        Port:          7079/TCP
        Host Port:     0/TCP
        Args:
          executor
        State:          Running
          Started:      Thu, 28 May 2020 05:54:04 -0700
        Ready:          True
        Restart Count:  0
        Limits:
          memory:  16Gi
    ```
    
    ### Does this PR introduce _any_ user-facing change?
    
    Document change.
    
    ### How was this patch tested?
    
    N/A
    
    Closes #28862 from yuj/patch-1.
