bootapi-images builds the AlmaLinux node rootfs tarballs that bootapi's
image-based provisioning (liveimg) unpacks, and on a v* tag publishes
almalinux9-node-<ver>.tar.zst to the artifactapi rootfs-images local repo. Split
out of bootapi-templates so that repo stays templates-only.
Modeled on the bootapi-templates entry: public, squash, delete-branch-after-merge,
main protection requiring the pre-commit + lint Woodpecker checks and benvin
approval.
