Updated deprecated helm chart source: https://kubernetes-charts.storage.googleapis.com

In Dec. 2020, Helm moved their repo away from https://kubernetes-charts.storage.googleapis.com. See this article. As a result, the dependencies pulled in from requirements.yaml no longer work (access is denied). The upstream GitLab requirements.yaml changed the source a couple of months ago. See this, this and this.

I updated the three spots (the GKE script was probably not necessary) referencing the old source to align with the new repositories. I did NOT change the versions used, so theoretically this should operate the same as it did before. Eventually, when we update the upstream helm chart, the changes will be pulled in from the upstream source.

I have tested this with k3d on AWS using the Big Bang umbrella to deploy.
