Informs #106068.
Epic: CRDB-29380

Before this patch:
```
$ cockroach start-single-node --config-profile=help
...
replication-source                  configuration suitable for a replication source cluster (alias for "multitenant+app+sharedservice+repl")
replication-target                  configuration suitable for a replication target cluster (alias for "multitenant+noapp+repl")`
multitenant+app+sharedservice       multi-tenant cluster with one secondary tenant configured to serve SQL application traffic
multitenant+app+sharedservice+repl  multi-tenant cluster with one secondary tenant configured to serve SQL application traffic, with replication enabled
multitenant+noapp                   multi-tenant cluster with no secondary tenant defined yet
multitenant+noapp+repl              multi-tenant cluster with no secondary tenant defined yet, with replication enabled
```

After this patch:
```
replication-source              configuration suitable for a replication source cluster (alias for "virtual+app+sharedservice+repl")
replication-target              configuration suitable for a replication target cluster (alias for "virtual+noapp+repl")
virtual+app+sharedservice       one virtual cluster configured to serve SQL application traffic
virtual+app+sharedservice+repl  one virtual cluster configured to serve SQL application traffic, with replication enabled
virtual+noapp                   virtualization enabled but no virtual cluster defined yet
virtual+noapp+repl              virtualization enabled but no virtual cluster defined yet, with replication enabled
```
