docs: update E2E Headlamp image namespace to headlamp-plugins

Updates ghcr.io/headlamp-k8s/headlamp → ghcr.io/headlamp-plugins/headlamp
in deploy-e2e-headlamp.sh (echo output and kubectl YAML image ref).

Note: .github/workflows/e2e.yaml also references headlamp-k8s/headlamp
but workflow files are Hugh's domain per SDLC rules.
