Description
The arm64 container currently builds in an emulated arm64 host via qemu-user. It would be much more efficient to cross-build from amd64 by having the Dockerfile specify FROM --platform=$BUILDPLATFORM for the builder container and set GOARCH=$TARGETARCH. However, Buildah < 1.24.1 doesn't support --platform in FROM. Once a new enough Buildah has landed in ubuntu-latest, switch to cross-building, and re-enable arm64 container builds in PRs by dropping the pr-arches override.

Research direction
Start with the Dockerfile builder stage and the CI configuration that defines the pr-arches override; verify the ubuntu-latest Buildah version before changing them. Done means amd64 builds cross-build the arm64 ignition-validate container and arm64 container builds run in pull requests without the override.
