Eval got merged. We can also start using the json.

I would add that instead of fetching @ofborg's evaluation result, if available it should fetch our new CI evaluator. https://github.com/NixOS/nixpkgs/actions/runs/11947073470/job/33302502332?pr=357763

So much todo and so little time :). If you want to take a step at it, I wouldn't mind. We can even check for both ofborg and the github one so it also works for older PRs that haven't been updated. However we don't have that json for master yet.
