Using `helm dependency update` may result in unwillingly updating the
dependencies while cutting a release. I wasn't able to do so. Most
likely due to the dependency pinning in Chart.yaml and Chart.lock.
Based on Helm documentation, `update` uses Chart.yaml[^1] while `build`
uses Chart.lock[^2].
All in all it is safer to use `helm dependency build`. :D
