[receivercreator] fix typo in examples (open-telemetry#30227)

fix typo in examples, since the `observe_nodes`, `observe_services` is [default](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/extension/observer/k8sobserver/README.md) to be `false`, so the receiver creator who wants to add endpoint of k8s.node and k8s.service will not work if the two config is `false` --------- Co-authored-by: Alex Boten <[email protected]>
