Issue details

When iterating and deploying a Pulumi project rapidly, one can run into rate limits enforced by third-party repositories:

kubernetes:helm.sh/v3:Release (karpenter-controller):
    error: kubernetes:helm.sh/v3:Release resource 'karpenter-controller': property chart value {oci://public.ecr.aws/karpenter/karpenter} has a problem: GET "https://public.ecr.aws/v2/karpenter/karpenter/tags/list?last=...": unexpected status code 429: toomanyrequests: Rate exceeded; check the chart name and repository configuration.

This feature request is for an option to cache the Helm chart (or the metadata for the Helm chart, unsure which one is causing the limit to be hit), and to introduce an option that has the helm.Release resource use this cached data for a user-defined period of time before attempting to update it.
