Please add a comment to explain why this is needed. Also would be good to include a link to a go-containerregistry issue if we are reporting this as a bug there (since this hack can be removed if go-containerregistry can handle the this unexpected header).

Part of https://github.com/github/package-security/issues/1731
Use a custom transport to handle non-compliant 406 responses from APIs when attempting to reach the refferes. endpoint. If an API does not support the referrers API, we generally expect a 404 response, but we have seen a 406 response as well and want to handle that case.
