neo4j-doc-manager is out of date

[moxious]

This page: https://neo4j.com/developer/neo4j-doc-manager/

referneces code in this repo: https://github.com/neo4j-contrib/neo4j_doc_manager

which is long dead and not functional, giving rise to user questions on the community site like this: https://community.neo4j.com/t/how-to-use-mongodb-along-side-neo4j-to-get-predictions/52887/4

which can't be answered. Recommend deprecating/removing the doc manager page, as more updated guidance isn't available.
