--version flag - Auto-DevOps.gitlab-ci.yml

https://gitlab.com/gitlab-org/gitlab-ci-yml/blame/master/Auto-DevOps.gitlab-ci.yml#L608

Any idea why --version flag is used here ? @nolith @mayra-cabrera @DylanGriffith ?

The auto-deploy-app chart wouldn't have this version "$CI_PIPELINE_ID-$CI_JOB_ID"

helm help upgrade

Flags:
--version string           specify the exact chart version to use. If this is not specified, the latest version is used
