Cross platform build with Kaniko

[mickkael]

Hi community !
I love Kaniko and use in multiple Argo workflows.

I have to build arm32 containers, and I have arm64 hosts available only.
With Docker, I am able to run
docker build -f Dockerfile_arm -t --platform linux/arm /tmp/source/

I am not sure I check the right part of the code, but it seems like Kaniko is taking the platform from the environment and doesn't allow to change.

kaniko/pkg/image/image_util.go

Line 205 in 46f270b

Architecture: runtime.GOARCH,

Please confirm I have on the right lead, and I can try a Pull request to add an argument in Kaniko to specify the platform
