Helpers for (agribalyse) categories game

[CharlesNepote]

Problem

I have tried the "Tomatoes" category but it was not so simple...
https://hunger.openfoodfacts.org/questions?value_tag=en%3Atomatoes&type=category&campaign=agribalyse-category&undefined=en%3Abelgium&sorted=true

• "Tomato sauce" => No.
• Are "tomato juices" or "crushed tomatoes" tomatoes? I would say no but "skip"ed.
• Are "chopped tomatoes" / "diced tomatoes" tomatoes? I'm not sure! I would say no but I "skip"ed.
• Are "dried tomatoes" tomatoes? I would say yes but I'm not completely sure (and I'm wrong) 😞

Proposed solution

It would be awesome to have a helper for each category with examples of what's in and what's out. For the data-quality facets we have a description for each one, see https://world.openfoodfacts.org/data-quality-error/nutrition-value-total-over-105
In the #taxonomies channel I also see many discussions on what products belong to what categories. Adding a description for each... A solution could be to let us see a small part of the categories graph allowing to see what are the parents, the children, and the siblings. Or even a YAML file style.

- Tomatoes and their products
  - Tomatoes
    - Canned tomatoes
    - Fresh tomatoes
    - ...
  - Dried tomatoes
  - Tomato juices
  - Tomato pulps
