chore: fix assets bundling integ test

[otaviomacedo]

In this test, the platform specified to bundle the asset is linux/amd64. But the image used doesn't specify any platform. This is causing the integ.assets.bundling.docker-opts.ts to fail with the message:

Unable to find image 'cdk-66687611b68d3de0f92ed971e4c457e4828f2e0c877c8b1f5fab42ac3d2772ec:latest' locally
docker: Error response from daemon: pull access denied for cdk-66687611b68d3de0f92ed971e4c457e4828f2e0c877c8b1f5fab42ac3d2772ec, repository does not exist or may require 'docker login'

Run 'docker run --help' for more information

Add the platform to the build parameters of the Docker image.

Does this not require snapshots to be updated?
