[Backport release-0.5] Correct what the telemetry guide says about egress and credentials - #508

Three claims in one paragraph of the shipped guide are wrong, and the third is about where a user's credential is held. "Your clusters reach the control plane, and only the control plane reaches your backend." Modelplane composes a collector onto each inference cluster and no collector onto the control plane. Each cluster exports to the sinks itself. "A cluster with no route to your observability stack still reports." It does not. Without a route to the backend it exports nothing. "The backend's credential lives in one place instead of on every GPU cluster." The opposite is true, and deliberately so: compose-serving-stack resolves the Secret a sink names and composes a copy onto every cluster that runs a collector, because the collector mounts it there. A reader deciding whether to give Modelplane a vendor token would have read this and been wrong about where the token ends up. The guide elsewhere describes the copy correctly, so this paragraph is the one place that contradicts both the code and the rest of the page.
