fix: update Elasticsearch to 8.5.0 and ES_VERSION to v8

The docker-compose smoke test ("Ensure images work") was failing because
auto-setup had ES_VERSION=v7 while running ES 8.0.0. This mismatch caused
the auto-setup container to get stuck waiting for Elasticsearch.

This fix was applied to release/v1.29.x in PR #309 but was never applied
to main, causing CI failures on all release branch PRs since
docker-build-only.yml checks out main.
