### Please describe the bug 🐞

Per hudi-hive-sync docs, since we're talking about HMS sync, isn't the command something like

```
./run_sync_tool.sh \
--metastore-uris 'thrift://hive-metastore:9083' \
--partitioned-by city \
--base-path 's3a://warehouse/people' \
--database hudi_db \
--table people \
--sync-mode hms
```

Open the “Register the target table in Hive Metastore” section at https://xtable.apache.org/docs/hms#register-the-target-table-in-hive-metastore and compare its example with the hudi-hive-sync documentation. Update the example to use the HMS sync command described in the issue, including the metastore URI and --sync-mode hms. Done means the page shows the correct HMS sync command.
