Well I just tried to make a repro by grabbing a random repo I had, but I get "Invalid authentication (as an anonymous user)" when trying to get a package from a GitHub registry, after configuring my scope with `yarn config set npmScopes.MYSCOPE.npmRegistryServer "https://npm.pkg.github.com"` and successfully logging in with `yarn npm login --scope MYSCOPE`.

Every single time I've tried Yarn 2 I end up frustrated.
