🔧 Update to latest docker template revision 🔧

- .env.scripts: synced version stamp to current template
- Dockerfile: fixed trailing space in PACK_LIST; restored image.source LABEL to GitHub URL after gen-dockerfile mis-set it to Docker Hub
- rootfs/usr/local/bin/entrypoint.sh: regenerated from current template
- rootfs/usr/local/etc/docker/functions/entrypoint.sh: replaced from current template
- rootfs/root/docker/setup/00-init.sh through 07-cleanup.sh: regenerated from current template
- rootfs/etc/profile.d/go.sh: migrated to rootfs/tmp/etc/profile.d/go.sh per current rootfs layout
- .gitignore: added rootfs/tmp/ exception so migrated rootfs/tmp files stay tracked
