v14.0.0rc4

What's Changed

feat: introduce COURSEGRAPH_RUN_NEO4J setting

Allows plugin users to disable the Neo4j service
so that they can self-host it instead, while still
being able to use the aspect of tutor-contrib-coursegraph
which configures CMS to dump course content.

The use-case here is that some users may be
dissatisfied with Neo4j's basic authentication
and would rather host restrict ingress Neo4j traffic
to, for example, an internal employees-only network.
