Fix cart thumb images resolution.

I guess we will want to move the function to a VTEX specific folder and be more clever to decide the image size.
Based on https://github.com/vtex-apps/checkout-graphql/blob/9b4959bf7b36971f2a1e2449cd7a108ff10b728f/node/utils/image/vtex.ts

Nice! However, I didn't want to move this computation to the frontend. Don't they have a config to do it on VTEX API side? AFAIK each store has a default checkout image size that the checkout API responds. If there is such a config, I'd rather go with it and remove this computing from the frontend

I know it's hard to believe but I don't think it exists for images returned in the orderForm. We always did this string manipulation in the cart, old (Knockout.js) and new. 🫠
