fix: indicate some attributes have only mandatory / not_important opt…

…ions (#10846)

This changes the result of
http://wold.openfoodfacts.org/api/v2/attribute_groups to add a "values"
array to list the possible values for each attribute.

Fixes #9370

Most attributes have 4:

values: [
"not_important",
"important",
"very_important",
"mandatory"
]

Allergens + vegan and vegetarian have 2:

values: [
"not_important",
"mandatory"
]
