fix(workflow): improve release workflow with version check and discord notifications (#369)

- Split semantic-release into version-check (dry-run) and release jobs
- Docker images now build before the actual release is created
- Use cycjimmy/semantic-release-action@v4 for better output handling
- Add Discord notification job to announce new releases
