Add Neo4j plugin.

[Jedore]

• If adding a new plugin, add a component id in the main repo. As Add Neo4j component language: Python skywalking#10937

• If adding a new plugin, add a logo in the UI repo

• I have added the library to pyproject.toml (plugin group) by running poetry add neo4j --group plugins

• I have rebuilt the Plugins.md documentation by running make doc-gen

• If this pull request closes/resolves/fixes an existing issue, replace the issue url. Closes: [Feature] [Python] Add Neo4j plugin skywalking#10898

• Update the CHANGELOG.md.

Something about the plugin,
The major Neo4j DBMS versions are 5 and 4.4. The latest neo4j python driver version is 5.x.x which support both Neo4j DBMS 5 and 4.4 . And python driver 4.4.x differs much from 5.x.x .So the neo4j plugin only support neo4j python driver 5.x.x.
Reference:

"The latest 5.x driver supports connection to any Neo4j 5 and 4.4 instance, and will also be compatible with Neo4j 6." in https://neo4j.com/docs/python-manual/5/install/

Neo4j python driver 5.x.x provide two method Session.run()&Transaction.run() to execute Cypher statement with both sync and async mode. tests/plugin/data/sw_neo4j/services/provider.py contains these four cases:

1. sync Session.run()
2. sync Transaction.run()
3. async Session.run()
4. async Transaction.run()

@Jedore Thank you! Generally looks great! Please add the neo4j dependency to poetry plugins group as indicated in the PR template. And if you would like maybe also add a note in the neo4j plugin (You see there's a variable called note there), to indicate only the 5.x driver is supported and its fine since it can support both DBMS versions.

@Superskyyy Thanks great! Please review the note and prproject.toml.
