Modify (or duplicate) the behaviour of the Nutri-Score attribute to make it compatible with Nutri-Score v2

[teolemon]

Problem

• I almost missed the Nutri-Score v2 in the app because the Attribute is still showing the classic logo, and linking to the classic label
• Now that moderators can get custom results from the server when they are logged in, we could have the attribute route return the new logo/panel for moderators
• We can either Modify the behaviour of the Nutri-Score attribute to make it compatible with Nutri-Score v2 for moderators. Alternatively we can return an additional attribute just for moderators.
