Support GitHub container registry

[MJRichardson]

Technically Octopus already supported GHCR, though you would never guess it from the experience of trying to configure it.

GHCR has not (yet) implemented the Docker catalog API which allows search for repositories.

This is resulting in the UI not behaving nicely when:

Testing the feed:

Selecting packages:

Creating releases:

The actual deployment (or runbook run) proceeds fine, as docker pull is supported.

We need to make the UI handle this situation more gracefully.

UPD: solved one issue by prefixing package name with the username (package owner) like arublevsky/sound-mastery-client then it works fine - it finds packages. But still deployment fails with the error The Docker Registry v2 'GitHub Container Registry' at https://ghcr.io does not support downloading packages on the Octopus Server.

@MJRichardson hey, I'm trying to use GHCR for my deployments but it fails to download the package and I can't solve that problem:
When creating a release I'm getting this error:

When trying to deploy it:

My feed settings:

Actually GHCR URL should contain a user name (docker push works fine for it ghcr.io/arublevsky/sound-mastery-client:${APP_VERSION) but I haven't find a way to set it up somewhere, so I'm kinda stuck 😞. Can you help me with this? Is there a documentation describing GHCR setup somewhere?

Hello fellows, I see I cannot use Github container registry using PAT (personal access token) authentication :) I need this because I've got enabled 2FA auth on organization account.. :(

I'm searching for a similar thing. Can't we use an access token instead of user credentials?
