ci: consolidate release-pipeline bash into tested Go #4

	name: "Test - Release Tooling"

	# Gates the Go that the release pipelines depend on (scripts/camunda-core +
	# scripts/release-tools). Deliberately UNFILTERED: the tooling's behavior is
	# coupled to inputs that live outside scripts/ (charts/*/values.yaml,
	# charts/chart-versions.yaml, the committed version-matrix, the release-please
	# trace + Harbor API shapes), so a chart-only PR must still run these tests.
	# A `go test` run is seconds; always-run cannot be skipped by a chart-only PR.

	# values here — catching chart-side structural drift at PR time, with no
	# `helm template` render.
