ci: install Helm with script located on GitHub

Installing Helm fails often in the CI. The Helm documentation does not
point to `https://git.io/get_helm.sh` anymore, but to a location on
GitHub. To make it easier to update the location in the future, it has
now been added to `build.env`, just like the `HELM_VERSION`.
