chore: update neo4j python driver to 6.0.0

[IlyaasK]

Summary

This PR updates the Neo4j Python driver dependency to allow version 6.0.0 (<7.0.0). It addresses the deprecation of read_transaction and write_transaction methods by migrating all occurrences to their modern equivalents, execute_read and execute_write, ensuring compatibility with the new driver version.

Checklist

Provide proof that this works (this makes reviews move faster). Please perform one or more of the following:

• Update/add unit or integration tests.
• Include a screenshot showing what the graph looked like before and after your changes.
• Include console log trace showing what happened before and after your changes.
  If you are changing a node or relationship:
• Update the schema and readme.
  If you are implementing a new intel module:
• Use the NodeSchema data model.
• Confirm that the linter actually passes (submitting a PR where the linter fails shows reviewers that you did not test your code and will delay your review).
