Add helm to distribution_ci_tools image

Why

Addressing gitlab-org/charts/gitlab#6419 (closed),

The release_package CI job in gitlab-org/charts/gitlab uses the distribution_ci_tools image and calls scripts/wait_for_charts_availability.sh, which requires helm. The image currently does not include helm, causing the job to fail.

Failed job: https://dev.gitlab.org/gitlab/charts/gitlab/-/jobs/35772796

What changed

• Added HELM_VERSION=4.1.4 to docker/VERSIONS
• Created docker/snippets/helm (for both amd64 and arm64) snippet following the same pattern as kubectl
• Added helm to the snippet includes in both Dockerfile_distribution_ci_tools.erb and Dockerfile_distribution_ci_tools_arm64.erb
