Apple Silicon aws-mwaa-local-runner produces plugins with aarch64 wheels Instead of x86_64

[MatusChladek]

When using aws-mwaa-local-runner on Apple Silicon Macs (aarch64) to build and package the environment, the resulting plugins.zip contains wheels built for aarch64 architecture instead of x86_64. This results in compatibility issues for users expecting x86_64 wheels.

Steps to Reproduce:

$ uname -m
> arm64
$ ./mwaa-local-env build-image
$ ./mwaa-local-env test-requirements
$ ./mwaa-local-env package-requirements

Steps for a fix:

Replace

docker build --rm --compress -t amazon/mwaa-local:$AIRFLOW_VERSION ./docker

by

docker build --rm --platform linux/amd64 --compress -t amazon/mwaa-local:$AIRFLOW_VERSION ./docker
