Update image used got GitLab ci
Overview
Other charts projects such as
https://gitlab.com/charts/gitlab/blob/82d5fd9f83c6b75a18eccd26cb26c875547d56f1/.gitlab-ci.yml#L27
use the
registry.gitlab.com/gitlab-org/gitlab-build-images:gitlab-charts-build-base
with a more up to date image and helm version.
This also consolidates our CI to be the same as the official GitLab Chart
