[KYUUBI #2150] [DOCS] Fix Getting Started With Kyuubi on Kubernetes

### _Why are the changes needed?_

helm安装kyuubi服务完成后会提示：
```script
NAME: kyuubi-helm
LAST DEPLOYED: Wed Mar 16 13:14:32 2022
NAMESPACE: kyuubi
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:

......

Get kyuubi expose URL by running these commands:
  **export NODE_PORT=$(kubectl get --namespace kyuubi -o jsonpath="{.spec.ports[0].nodePort}" services kyuubi-helm-nodeport)**
  export NODE_IP=$(kubectl get nodes --namespace kyuubi -o jsonpath="{.items[0].status.addresses[0].address}")
  echo $NODE_IP:$NODE_PORT
```

使用命令
```
export NODE_PORT=$(kubectl get --namespace kyuubi -o jsonpath="{.spec.ports[0].nodePort}" services kyuubi-helm-nodeport)
```
会得到一个报错：
```
Error from server (NotFound): services "kyuubi-helm-nodeport" not found
```
使用`kubectl get svc -A`，查询到namespace：kyuubi下只有一个service："kyuubi-svc"，运行
```
export NODE_PORT=$(kubectl get --namespace kyuubi -o jsonpath="{.spec.ports[0].nodePort}" services kyuubi-svc)
```
成功。so这里给的serviceName是否是错的？

### _How was this patch tested?_
- [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible

- [ ] Add screenshots for manual tests if appropriate

- [ ] [Run test](https://kyuubi.apache.org/docs/latest/develop_tools/testing.html#running-tests) locally before make a pull request

Closes #2150 from HYBG-1126/HYBG-1126.
