Can't install neo4j without neo4j-community

Downloading neo4j-9.4.0 revealed dependencies not in the API or the lockfile (neo4j-community (~> 2.0)).
Either installing with `--full-index` or running `bundle update neo4j` should fix the problem.

Same result with --full-index
bundle update neo4j gives: Unable to find a spec satisfying neo4j (~> 9.4.0) in the set. Perhaps the lockfile is corrupted?

Relevant bit of the Gemfile.lock:

    neo4j (9.4.0)
      activemodel (>= 4.0)

If I manually add neo4j-community in, it works... but since we're not on JRuby we don't add that library into our dependency graph..
