Hello team,

My team encountered an issue in Fluxcd (fluxcd/flux2#4804) that seems to be related to an issue that was already solved here (#11426). When trying to replicate the solution there, I saw on the code that the retryingRoundTripper is private to the helm cli package (https://github.com/helm/helm/blob/main/pkg/cli/roundtripper.go#L27).

Can we make it public? Do you guys see any issues on doing this?
