Documentation for creating new tenants is incorrect

Existing steps to create a new tenant for e.g a server tenant: https://docs.pinot.apache.org/basics/components/tenant#server-tenant don't seem to be correct and invoking the actual API endpoint (/tenants) returns a 400 error even if there are untagged servers available in the environment. For e.g below payload

{ "tenantRole" : "SERVER", "tenantName" : "Demo", "offlineInstances" : 1, "realtimeInstances" : 0 } with a single untagged server available in cluster, yielded below error:

{ "code": 400, "error": "Cannot request more offline instances: 1 or realtime instances: 0 than total instances: 0" }

In addition there is no reason why you can't have more than one tag assigned to same server, so not sure if below in documentation is correct: "The creation will fail if number of untagged server nodes is less than offlineInstances + realtimeInstances."

When you do this through the Pinot console then it actually calls a diff. API endpt. (/updateTags) vs. what's in docs. @mayankshriv @npawar can we please review if above is accurate conclusion and fix the docs ?
