feat: script to filter and generate raw categories (with translations)

[raphodn]

What

Script to automatically :

• filter the taxonomy categories to keep only the "raw" ones (needed for the price add form + price display)
• generate the language specific fields

Output

Total number of categories: 12854
Filter with the following parent categories: [<TaxonomyNode en:vegetables>, <TaxonomyNode en:fruits>, <TaxonomyNode en:culinary-plants>, <TaxonomyNode en:nuts>, <TaxonomyNode en:potatoes>, <TaxonomyNode en:textured-vegetable-protein>]
Add extra nodes: ['en:rolled-oats', 'en:ginger', 'en:mushrooms']
Additional filtering on: ['Cooked ', 'Fresh ']
Categories remaining: 579
Wrote to language files

185 json files in src/data/categories/<language-code>.json

I would rather have this script in the backend and have a mechanism to fetch the needed data and store it in the store. But good for now!
