Azure blob storage copy doesn't work since Azure CLI 2.66+

### Describe the bug

https://github.com/Azure/azure-cli/pull/29964
Hi @calvinhzy, @yonzhan,

I wanted to bring to your attention an issue we've been experiencing with the Azure DevOps CLI since the release of version 2.66. Our task to copy blobs no longer works.

Could you please provide some insights into what might have changed in version 2.66 that could be causing this issue? Any guidance or suggestions to resolve this would be greatly appreciated.

Thank you for your assistance!
