Deploy a Helm step needs better output to logs

Severity

I could reproduce the problem in the latest build

What happened?

The customer reported that Helm warnings during deployments in Octopus are only visible when verbose logging is enabled, which undermines the purpose of validation warnings. They are using the built-in "Deploy a Helm Chart" step and cannot modify CLI arguments. Helm redirects STDERR/STDOUT in ways that complicate capturing warnings in Octopus and suggested workarounds for custom scripts, but these do not apply to the built-in step.

Reproduction

Default usage of Deploy a Helm chart exhibits this behaviour.
