feat: Hunger logo game search button

[DanieliusAsm]

What

• Added a button that sends you to https://hunger.openfoodfacts.org/logos/search?barcode=
• This button is shown only when you choose to list barcodes. That is because that functionality adds data-code (barcode) for all of the products. It was easier to reuse what was already done. Will need to recode that part so it is no longer needed to see the hunger link.

• I didnt know about the version thing since I dont have prior expeirience to User scripts.
• I planned to make this change in the future. I would want to add more buttons so there should be a toggle (maybe not for this hunger game button). Ideally I would want to add buttons: rotate left, rotate right, delete buttons if I could figure out the rotation stuff
• The delete button would be seen by everyone not just mods so thats problematic as there is no way of knowing if a user is a mod. It should probably be hidden by default and be toggleable

Yes we should document development process a little bit.

Great! Have you seen: https://openfoodfacts.github.io/openfoodfacts-server/api/ref-v2/#get-/cgi/product_image_crop.pl

The delete button would be seen by everyone not just mods so thats problematic as there is no way of knowing if a user is a mod. It should probably be hidden by default and be toggleable

There is an ongoing bug here that would allow you to test if a user is an admin or not: https://github.com/openfoodfacts/openfoodfacts-server/issues/6758
