"devcontainer features publish" fails to log in with Artifactory

[imphil]

We're using Artifactory as container registry and I'm trying to use it to store a Dev Container Feature. Unfortunately, the login fails.

I have setup a Docker credential helper to return the username and token, but we're not even getting there:

The scope key is not part of the response, which seems to be allowed according to https://datatracker.ietf.org/doc/html/rfc6750#section-3 (as referenced in https://distribution.github.io/distribution/spec/auth/token/).

I'm not even close to understanding how the auth flow works, so I'd appreciate further input on that.

Container Registry: Artifactory Enterprise Plus 7.55.8 rev 75508900

With #692 I'm able to successfully push a feature to Artifactory.
