Done. Next steps:
  1. git add -A && git commit -m "Initial commit" && git push
  2. On GitHub: Settings > Actions > General > Workflow permissions
     -> enable "Read and write permissions" so the workflow can push packages
  3. Actions > "Watch for Factorio releases" > Run workflow
     -> publishes the first images; after that it runs on its own schedule
  4. Once published, make the package public:
     the repo's Packages sidebar > package settings > Change visibility
