Since the images are created by AWS, this just makes more sense. Also, the images for the latest Python runtime (3.14) are not on Docker Hub for some reason.

Pull request overview
Switches the base image source for both Dockerfile build stages from Docker Hub (docker.io/amazon/aws-lambda-python) to AWS's public ECR (public.ecr.aws/lambda/python). This avoids Docker Hub rate limits and provides access to newer Python runtime images published only on ECR.
Changes:
- Update
install-stagebase image topublic.ecr.aws/lambda/python:3.9. - Update
build-stagebase image topublic.ecr.aws/lambda/python:3.9.
