ci: run integration tests against Weaviate 1.39.0-rc.0

Bumps the integration-test matrix from 1.36.x to 1.39.0-rc.0 and adds the
version to the test-package matrix. There is no plain `1.39.0-rc.0` tag on
Docker Hub yet, only commit-suffixed builds, so the newest one is pinned
following the existing `WEAVIATE_137` convention.

One existing test needed adapting to an intentional server change in 1.39:
`asyncEnabled` is no longer stored per class but derived server-side as
`factor > 1 && !globallyDisabled`. `test_collection_config_full` uses a
replication factor of 1, so the field now reports `False`. The pre-1.39
assertions are kept behind a version check.
