devdocs/build/RELEASE-PROCEDURE.md replaces John's notes from several info
cases: release order with subscription droplets upgraded before the
announcement, git tagging, scp uploads, the download-back check, upgrade
commands with curl -f, the one-time 8.3.0 droplet steps (harden-830.sh), the
weekly OS update and the full version bump list. BUILD.md's partial version
table now points to it.
