[Bug]: Empty path generated by typespec-autorest emitter

[catalinaperalta]

Describe the bug

The typespec-autorest emitter outputs an empty path for an operation definition like the following: playground example

I believe this type of operation should be generated under x-ms-paths but at the very least it should output a path like "/" since the operation is at the root of the endpoint.
