This is unnecessary hard in shell when compared to a proper programming language. It becomes even easier with a node-js script, as that gives us access to the underlying ESLint module rather than just the CLI interface. Besides that, node-js has the added benefit that we don't need to add more dependencies to the CI image. https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1497
