Summary

Added IAM authentication section and removed note about gremlinpython version compatibility

Security assessment

The change adds documentation about IAM authentication for Neptune, which is a security feature for controlling access to DB clusters. It provides guidance on using Signature Version 4 signing for authentication. However, there is no evidence that this change addresses a specific security vulnerability or incident; it appears to be routine documentation improvement.
