Replace py2neo fork with official Neo4j driver

[UsamaSadiq]

Description

• The official PyPI release of py2neo has been removed from PyPI
• The official GitHub organization has been archived so the package is no longer available on any platform.
• The PR fix: replace py2neo with forked package #33453 replaced the py2neo package with the most recently available fork to resolve the dependency blocker in edx-platform.

TODO

First, choose a new library to replace py2neo. Options discussed:

• official Neo4j driver
• neomodel

Then:
Replace the py2neo with the chosen library and make sure the related functionality is working fine.

In a small-world moment, the author of py2neo said to me on social media:

I have now handed over all the project assets to Neo4j, in return for them making a charitable donation.
They have taken the project into their "contrib" area and will now actually be re-releasing packages, and potentially moving some functionality over to their official driver.
