[DEPR]: Remove Neo4J Support #34342

[qasimgulzar]

Issue

Proposal Date: 2024-03-07 Target Ticket Acceptance Date: 2024-03-21 Earliest Open edX Named Release Without This Functionality: Sumac 2024-10

Rationale

This pull request addresses the removal of Neo4j support from the edx-platform, along with the associated dependencies and the coursegraph app. The decision to deprecate and remove this functionality stems from the observation that Neo4j usage is underused and not deemed particularly valuable, with many operators transitioning to alternative data stores for course data search.

Changes Made

1. Removal of Neo4j dependencies.
2. Removal of the coursegraph app from cms.djangpapps.coursegraph.

Replacement

There is currently no direct replacement proposed for the functionality being removed. However, users interested in retaining this functionality can explore creating a separate plugin.
