How to describe HTTP equivalent status codes in auth2

[zimeon]

In the Auth2 branch we currently use "HTTP equivalent" status codes for the probe service status. We describe these as "The HTTP status code that would be returned for the resource for which this is a Probe Service.". However, in the video 302 / location example, the likely actual response would be 401 if one tried to access the original access-controlled resource ... but we still want to treat it like a 302 and access the location

Resolved. In Auth 2.0 have Probe Service where status is described as "The HTTP status code that would be returned for the access-controlled resource.". The location property must only be included for 30x response https://iiif.io/api/auth/2.0/#location
