Related Issue or Design Document

In the documentation we indicate that a user can spin up the tunnel/proxy using the project ID or the project slug.

The project ID is not currently supported and will show the user an error

{"error":{"code":404,"status":"Not Found","request":"cf6a5564-bca9-95a8-8ec6-c04e8f2e16f1","reason":"The requested host is not associated with any Ory Cloud Project. Are you sure the URL is correct?","message":"The requested resource could not be found"}}

The tunnel/proxy only takes the --project flag and does string manipulation to add the project slug into the ory api string.
