release: v0.4.0

First tagged release of this fork. Adds the 0.4.0 changelog section covering the work since upstream 0.3.15, guards the Docker Hub publishing job behind a repository variable (no credentials are configured for that namespace), and stops auto-generated release notes in favour of the changelog body.
