Adopt framework v0.6.0 and call the shared script from the publish workflow

- framework moves from v0.5.2 to v0.6.0 (QC-YML-001, QC-WF-001, the YAML
  convention, the qc/artifacts and qc/code folders, autonomous mode, the CI
  publish script).
- .gitea/workflows/sync-milestones.yml: the two run blocks of six lines call
  framework/scripts/ci-publish-milestones.sh (ensure-tools, publish); QC-WF-001
  criterion 20. Same behaviour.
- CHANGELOG.md, Unreleased, Changed.
