The high-level Elasticsearch client currently bundled with Quarkus only supports ES 7, and we can't upgrade to a new version of that client because it's no longer open-source.

So, unfortunately, we might need to wait until #22622 is merged, because it introduces the replacement client which should officially support ES 8. That would mean waiting until Quarkus 3 (see PR for reasons).

I'm open to suggestions, but since the present issue is only about changing a default that can be overridden by users anyway, I think it's not worth taking too much risks (like trying to make the old high-level Elasticsearch client work with ES 8).

ok, let's wait for #22622
