alloy-app release v0.21.1

Fixed

• Setting alloy.enabled: false now disables the whole chart on its own and renders nothing. Previously it only dropped the upstream Alloy chart, and the Giant Swarm templates (NetworkPolicy, Kyverno PolicyException, VerticalPodAutoscaler, PodLogs, extra env Secret) failed to render with no template "alloy.chart" associated with template "gotpl" unless networkPolicy.flavor and kyvernoPolicyExceptions.enabled were also overridden.

Added

• Add a make test-chart target and a test-chart workflow that render the chart with every ci/*-values.yaml file and assert it renders nothing when disabled and all of its objects when enabled. Unlike ct lint, these use a current Helm, which is required to catch template rendering errors.
