This adds a few country entries to specific labels.

Ecocert Canada -> Assumption is they would only certify canadian goods
Bio Austria -> As above
French brands -> Assuming they are products of France

I think they need "country:en:" as the prefix.

We need to think carefully about what we exactly want to achieve here. We currently do not have a "country of origin" field (as in the product was made in that country). We could add one. Currently we use labels for that: "Made in Belgium".

We have a "origins of ingredients" field where we put countries, but that's something else entirely.

Also we should not make any assumptions without verifying them. It's very possible that Bio Austria etc. certify products that are imported. That does not mean they were produced in Austria.

Happy to reduce it to just the "Made in XYZ" labels for now; others later

I think they need "country:en:" as the prefix.

I wasn't sure on that, as other examples didn't use that approach and it seemed more prevalent. Will swap those over however.
