Dockerfile 'platform' argument in 'from' command seems to get ignored.

I'm on a Macbook Pro, with Apple M2 chip (ARM64).

I have a folder called 'devcontainer-test' in which a dockerfile is placed that contains the following:

FROM --platform=linux/amd64 pytorchlightning/pytorch_lightning:base-cuda-py3.10-torch1.13-cuda11.7.1

I can build this dockerfile without issue

docker build .

However, when I try to 'Open folder in container...', it fails to build, the log is shown below

The "no matching manifest for linux/arm64/v8" is the thing that causes me to think that the platform argument is getting ignored, since AMD is specified and not ARM64.

The workaround I found is to pin the docker image using the sha256, this requires changing the dockerfile to the following:

FROM pytorchlightning/pytorch_lightning:base-cuda-py3.10-torch1.13-cuda11.7.1@sha256:77a2b5267fa2a0d6877e59f7f6338879f51fac305eb963b3a3bca9d5c209f701

Doing so will cause the devcontainer to build properly.
