HttpBinaryCacheStore: Improve error message for unauthorized caches

Browse source 
Instead of the unhelpful

  warning: 'https://cache.flakehub.com' does not appear to be a binary cache

you now get

  warning: unable to download 'https://cache.flakehub.com/nix-cache-info': HTTP error 401

           response body:

           {"code":401,"error":"Unauthorized","message":"Unauthorized."}
