Add a human-merge label that keeps autopilot from merging

autopilot skips both human checkpoints: approval before the build and the
merge. Scheduled update issues in homelab want the hands-off build but a human
merge, since merging there deploys. With human-merge also on the issue, @pm is
told to hand back at phase 3 and publish.sh refuses MERGE_PR.
