(assets): Dockerfiles built on ARM do not run on Linux instances

### Describe the bug

Instead of:
```
FROM node:16-alpine3.13
```

Use:
```
FROM --platform=linux/amd64 node:16-alpine3.13
```

If building on an ARM machine, excluding `--platform` will result in an obscure deployment error.

### Expected Behavior

success

### Current Behavior

Deployment error

### Reproduction Steps

Run the EKS Integration test `integ.eks-service-account-sdk-call` with

```
FROM public.ecr.aws/docker/library/node:16-alpine3.13
```

at the top of the dockerfile.

Start with the Dockerfile used by the integ.eks-service-account-sdk-call EKS integration test and inspect how its Node image is built on ARM. Reproduce the deployment failure with the stated public ECR image, then verify that an ARM-built image deploys successfully to a Linux instance and that the integration test passes.
