Add a category for "prepared food with at least 80% milk" and account for it in nutri-score computation

[alexgarel]

Describe the bug

On https://fr.openfoodfacts.org/produit/3033710073467/ricore-original-nestle#panel_nutriscore we have a difference between advertised eco-score and computed one.

This is because this product Eco-Score is computed as prepared, but preparation involves milk, which makes it goes in a different category and therefore changes computation.

To Reproduce

see https://fr.openfoodfacts.org/produit/3033710073467/ricore-original-nestle#panel_nutriscore

Expected behavior

• Add a "prepared food with at least 80% milk" (or some better name) category (taxonomies/categories.txt).
• Change the nutriscore computation to account for this category (probably Food::is_beverage_for_nutrition_score)

In case of products prepared with milk, we should add this category.

Hello @alexgarel I'm willing to work on this issue but can you please attach a screenshot that where to add the "prepared food with at least 80% milk", I couldn't figure out where that section is present

[alexgarel]

@vedantmistryy it's a category (see category field, when you edit a product) but it does not exists yet, so it should be added to taxonomies/categories.txt, at the right place as a child of drink) see https://wiki.openfoodfacts.org/Global_taxonomies#format and you will have to "make build_taxonomy" to have it taken into account.
