Mitchell R 3746f685be ci: bump action versions to latest + add QEMU arm64 binfmt for pi-gen ... Real cause of last pi-gen failure was surfaced by verbose-output: WARNING: Only a native build environment is supported. arm64: not supported on this machine/kernel ubuntu-latest is x86_64; pi-gen builds an arm64 image and chroots into it during stages, requiring binfmt_misc handlers for arm64. Add docker/setup-qemu-action before the pi-gen step. While here, audit + bump every action version (pinned to current majors): actions/checkout v4 → v6 actions/upload-artifact v4 → v7 actions/download-artifact v4 → v8 softprops/action-gh-release v2 → v3 docker/setup-qemu-action @v4 (new) usimd/pi-gen-action @v1 (already current major) dtolnay/rust-toolchain @stable (rolling channel — keep)		2026-05-20 00:11:45 +02:00
