💡 The github-pages container doesn't work anymore

Why:
- It crashes with "Segmentation fault" on M3 Macbook. Looks like it's
  not compatible with ARM. Related issue:
  Starefossen/docker-github-pages#74
- Consider adapting the docker image (ghcr.io/actions/jekyll-build-pages)
  that GitHub uses for building the site in GitHub Actions.
- Consider merging the front page and user guide into the application,
  and get rid of the Jekyll site.
