refactor(kubernetes): remove envsubst due to expansion by gitlab
Due to https://docs.gitlab.com/ee/ci/variables/#use-variables-in-other-variables the variable expansion is already done by GitLab, so the need for envsubst
goes away.
Both KUBE_VALUES
and HELM_ARGS
are defined as variables:
inside the generated pipeline.
I assume the gettext-base package in the jobs-default image is also there becaus of envsubst
