What did you expect to happen?

The manifest and images to be pulled to my local workstation.

How can we reproduce it?

1. Install Rancher Desktop on a Windows 11 host machine
2. Install WSL2
3. Use rancher-desktop as your distribution for WSL2
4. Use docker login in the Windows host, so that your credentials are in the Windows Credential Manager
5. Run oras manifest fetch in the WSL2 shell against a public image of your choice
