AWS Lambda Python 3.9 runtime deprecated

[ego93]

Currently, the AWS serverless deployment is deployed with Python 3.9 runtime.

JumpCloud-Serverless/AWS/DirectoryInsights/serverless.yaml

Line 117 in 2f3e965

Runtime: python3.9

This has been deprecated as of December 15, 2025 and must migrate before December 15, 2025

I've successfully deployed this using Python 3.12 and can confirm it's working without issue.
