Duplicated slug for laitdevache

[Flaburgan]

Hello,
I had a bug in my app using the API because the route returning the drinks https://impactco2.fr/api/v1/thematiques/ecv/3?detail=0&language=fr is returning two items with the slug set to laitdevache, one with an ecv of 0.1505 and one with an ecv of 1.33. This is crashing my app as I use slugs as the unique ID.

I indeed find this laitdevache being defined twice in your data, once in boisson.json and once in alimentation.json, but I would have expect the drink route to not include the item from the alimentation.json (although I see there that it has the category set to 3, so I guess that's why it is included in this route).

In any case, I think it would be better to have the slug unique in the whole app, so I would suggest to remove the definition of laitdevache in the alimentation.json file. I initially did that in an MR but then I realized it is loaded in alimentation.ts so I guess it's better if you do it.

Thanks for your work!
