Add a panel of last answered robotoff questions

[alexgarel]

Problem

If we want to monitor an area of interest of the database, last edits are cool, but we, most of the time don't know exactly what changes.
Robotoff answered question are on the other side very precise: we have a question and an answer.

Proposed solution

Add a panel with last robotoff answered questions for products of those facets.

Additional context

A first possible simple way is to just concentrate on question concerning this facet and value.

But it means we do not see other questions about products of these facets. For this I don't have any solution ! We could cross with last edits, but this way we may get positive answers, but not negatives ones.

for category beers,
https://robotoff.openfoodfacts.org/api/v1/insights?insight_types=category&value_tag=en:beers&annotated=1&page=1&count=25
does part of the job, but we need sorting which is not supported by robotoff API right now.

We need to wait for openfoodfacts/robotoff#968
