### Proposed changes

<!--Give us a brief description of what you've done and what it solves.
-->
Closes #2644 

This PR fixes support for OCI charts on Windows, by making the code be
more consistent with Helm (see
[code](https://github.com/helm/helm/blob/main/pkg/action/install.go#L724)).
I believe the error comes from the call to `os.Stat` (see Golang
implementation which is based on CreateFile,
[here](https://go.dev/src/os/stat_windows.go)).
