ingredient_spellcheck HTML encodes original text incorrectly

[hangy]

What

It looks like Robotoff incorrectly encodes HTML entities in the JSON response (or potentially before sending them to the spellcheck API in the first place). This should be done in the Hunger Games frontend.

Steps to reproduce the behavior

1. Go to https://hunger.openfoodfacts.org/ingredient-spellcheck and randomly land on an insight for a product with potential HTML entities in the text, ie. 4025500283148
2. See that the " in the ingredients list is incorrectly encoded
3. Check the JSON response https://robotoff.openfoodfacts.org/api/v1/insights?lc=de&insight_types=ingredient_spellcheck&annotated=false and see that "" is already encoded as " in the JSON:

4.  {

    }

Expected behavior

The product text should only be encoded by the website, making parts of the suggested correction unnecessary.
