Some of the submodules here are slightly out of date. I was wondering if we perhaps want a GitHub Actions workflow that keeps the submodules pointing to the latest?

Something like https://github.com/xmonad/xmonad-web/blob/gh-pages/.github/workflows/submodule.yaml, or use an action from the marketplace, or something.
