To avoid conflicts between the Helm chart and KO image tags, we will push to the kong/kong-operator-chart repo. However, there is a limitation here: when pushing to OCI, the path must match the name of the Chart. We may need to modify the name of the Chart.

helm package charts/kong-operator
helm push kong-operator-${{ steps.kong_operator_oci.outputs.version }}.tgz oci://registry-1.docker.io/kong
