controller-manager, and scheduler server components, we no longer
  reference the individual architectures in the image names, specifically
  in the 'FROM' directive of the server image Dockerfiles.
  
  As a result, server images for non-amd64 images copy in the go-runner
  amd64 binary instead of the go-runner that matches that architecture.
  
  This commit explicitly sets the '--platform=linux/${arch}' to ensure

        `ResNetRS50`, `ResNetRS101`, `ResNetRS152`, `ResNetRS200`,
        `ResNetRS270`, `ResNetRS350` and `ResNetRS420` model architectures. The
        ResNetRS models are based on the architecture described in
        [Revisiting ResNets: Improved Training and Scaling Strategies](https://arxiv.org/pdf/2103.07579.pdf)
