Subject: [PATCH] fix(ci): replace heredoc JSON with printf in publish
 workflows
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The heredoc block writing Docker config.json had unindented `{` at
column 1, which GitHub Actions' YAML parser interpreted as a flow
mapping start — causing every publish-platform-image and
publish-canvas-image run to fail with 0 jobs (startup_failure).

Replace `cat <<'JSON' ... JSON` with a single `printf` call that
produces identical config.json content without confusing the parser.
