az acr build specifying --platform linux/amd64 is not working

[gvsireesh]

Describe the bug Hi Team, I'm trying to run az acr build task by passing parameter --platform linux/amd64, in the docker file we have FROM --platform=$BUILDPLATFORM mcr.microsoft.com/dotnet/nightly/sdk:8.0-preview AS build the build command throws exception if I pass --parameter value. Please find the error below, when I remove platform from command and dockerfile the az acr build command works perfectly.

Yes this is quite important for those of us on M1/2/3 macs because we need to put this in our Dockerfiles very often. If we're building something locally and pushing it, we often end up building for the wrong architecture without. It looks like the VSCode extension (with the referenced pull request above) simply replaces it with nothing -- could you do that on the Azure backend instead / in addition?
