Document how to add multi-arch support for the docker and podman templates #3733
Description
Description
Building for another architecture gets an error:
exec /bin/sh: exec format error
Currently there is documentation for containerd
https://lima-vm.io/docs/config/multi-arch/#fast-mode
Might need entries also for docker and podman:
limactl shell docker sudo apt install -y qemu-user-static
limactl shell podman sudo dnf install -y qemu-user-static
And some basic example with --platform linux/amd64
Might also need qemu-user-binfmt or something, verify that the packages actually enable the binfmt_misc entries:
/proc/sys/fs/binfmt_misc
It needs to be static to work in containers, otherwise it might have dependencies on host libraries that are unavailable.
i.e. it works for regular binaries in the VM
