Please update to node20; node16 is deprecated

[ddneilson]

I just saw a new warning when running this action:

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: aws-actions/aws-codebuild-run-build@v1. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.
