Keep the changelog workflow consistent with the new release heading.

CHANGELOG.md now starts with ## [v1.0.2], but CONTRIBUTING.md Lines 86-91 still instruct contributors to use ## [Unreleased]. Add a new ## [Unreleased] section above v1.0.2, or update the contributor and release-workflow instructions. Otherwise, future release notes can be omitted from the tag-specific section.
