This repo serves as a minimal reproduction example for a Renovate feature request with respect to Terraform data "helm_template" blocks.
Currently, Renovate is not able to detect updates to Helm charts when used inside of a Terraform data "helm_template" data source block. This is in contrast to a resource "helm_release" resource block which works perfectly fine.
Renovate should be able to detect new releases of Helm charts when used with a data "helm_template" and raise PRs for those changes as appropriate.
