[Bug]: The overload decorator does not recognize an operation that's in the same interface .

[catalinaperalta]

Describe the bug

This PR shows a use case where the overload decorator is used on an operation in the same interface, however seems like typespec doesnt recognize this: Azure/azure-rest-api-specs#40625

The error outputted is: https://github.com/Azure/azure-rest-api-specs/actions/runs/22248625832/job/64367679720?pr=40625#step:4:105

To get around it I attempted explicitly referencing the interface but the same error is reported.

Reproduction

Azure/azure-rest-api-specs#40625
