CI: Make helm-CI run for all changes (#1611)

Whether helm-charts work (or not) doesn't only depend on what's on the `helm/` directory, but also the production code. It's hard to figure out which changes could break the helm-charts or what the helm-charts rely on. Therefore it's likely better to run Helm-CI for all changes.
