Presentation Exchange OAuth is missing a readme file

[BenjaminMoe]

All of the other tutorials have a top-level readme file which describes the postman collection. Presentation Exchange OAuth only has the postman .json file. https://github.com/w3c-ccg/traceability-interop/tree/main/docs/tutorials/presentations-exchange-oauth

Given that this is the direction we agree on going (switching from DIDAuth to Oauth), this is a particularly important tutorial to add.

I have not been able to work on this tutorial yet.

[brownoxford]

No work as of yet, conformance testing has been taking higher priority.

[BenjaminMoe]

I'll make a ticket to review and work on this.

[nissimsan]

@BenjaminMoe to work on this.

[OR13]

We still need to create a readme for this.

Closing as done.
