GKE: build from this cluster's registry

Browse Source 
demo-go-app is the one demo app that ships its own Dockerfile, and that
Dockerfile names the registry — so unlike toolshed, whose source is
genuinely cluster-agnostic, this repo cannot serve both clusters from one
copy. Both stages now pull from harbor.35.238.248.203.nip.io.

Nothing else needed changing. The Jenkinsfile is two lines and resolves
whichever devops-lib the Jenkins running it has registered, and config.yaml
only exercises the pre/post-build hooks.

Both base images it needs, golang:1.22-alpine and alpine:3.20, are present
in devops-base-images-gcp's manifest — an unmirrored tag would fail the
build rather than quietly falling back to Docker Hub.
