[Helm/Release] Unable to create new release: `mkdir` error

@gf3 @viveklak I was running into the exact same issue (i9 MacOS) and managed to solve it by setting the PULUMI_K8s_HELM_REPOSITORY_CACHE env to a temporary directory.

It appears that this line returns an empty string in my environment, causing the mkdir executed by Helm to fail.

@viveklak i just tried upgrading, luckily there weren’t any required changes—unfortunately i’m seeing the same error

currently this is failing in my local dev environment (M1 macOS), which is the same environment i am able to successfully run helm/terraform to fetch and install the chart

Thanks for following up so quickly! Could you send me the logs post upgrade? That would really help. Interestingly I am not able to reproduce this locally (i7 macos) but I can’t see why the change in arch would matter.
