Unclear language in Couchbasecluster Resource

In The following docs

https://docs.couchbase.com/operator/current/reference-couchbasecluster-services.html#couchbase-srv

We have a paragraph describing the service, however, it's unclear wheather or not couchbase-srv exposes port 8091

In the section of `couchbase`, we have:

The first service that is created, it creates endpoints for every Couchbase node in the cluster on administration ports 8091 and 18091. It is a headless service so doesn’t create a virtual IP or offer any load balancing.

In the couchbase-srv section, it says:

This service is similar to the previous in that it creates endpoints for the admin ports and is headless. The key difference however is that this service is restricted to only the Couchbase nodes with the data service enabled.

While it does state that couchbase-srv is restricted to data node, the language makes it seem like it would also expose ports 8091, which is not the case, it only exposes port 11210.

We should have the descriptions cleaned up to avoid confusions from customer
