Looks like we've only build the container image for linux/amd64 which is backed up by https://github.com/Azure/data-api-builder/blob/main/.pipelines/build-pipelines.yml#L269-L310

We'll need to add a --platform flag to the task that generates linux/amd64 and linux/arm64, although I'm not sure how to do that with https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/reference/docker-v2?view=azure-pipelines&tabs=yaml

[aaronpowell]

Oh, looks like the task doesn't natively support it, nor has there been much traction to get it supported - microsoft/azure-pipelines-tasks#16491

Might have to fall back to using scripts within the pipeline to call Docker directly.
