"Cluster Deployment" contains stale information

Is your feature request related to a problem? Please describe. https://nacos.io/en-us/docs/v2/guide/admin/cluster-mode-quick-start.html "Cluster Deployment" contains stale information.

• in this doc it's using v1.3.0
• to deploy cluster mode, we need to specify external datasource (https://github.com/alibaba/nacos/issues/11015#issuecomment-1695669125) , but in the documentation there's no description about that.

Describe the solution you'd like update docs as mentioned above

Describe alternatives you've considered NA

Additional context If the doc is OSS, I'll submit PR, if so I'd glad if you provide me the location of the documentation repo link.
