yum update python not working in AL2 EC2 instance (from elastic beanstalk).

The security adivsory here https://alas.aws.amazon.com/AL2/ALAS-2022-1802.html indicates that the AL2 Python package has been patched and an update is available (in python-2.7.18-1.amzn2.0.5.aarch64). The adisory directs:

Issue Correction:
Run yum update python to update your system.

However, executing yum update python does not update the package - no update to the package is found. Why is the package update not applied?
