`exposeHostPorts`'s worked example told the operator to set
`services.hyperhive.otel.endpoint` to a bridge address. That was true
before the collector tiers existed. It is now actively wrong: `enable`
contributes the hive collector's port to this list itself and derives
the agent-facing endpoint, while `endpoint` names where telemetry goes
after it leaves the swarm and is read by the swarm's collector. An
operator following the old example would point the upstream link at a
bridge address.
Replace it with an example that is actually the option's job -- a
host-local service the operator runs themselves -- and say plainly that
hyperhive's own telemetry needs nothing here, which docs/observability.md
already states.
