### Bug description

Trying to generate a listing or custom listing in formats other than a Quarto project: website silently fail and doesn't do anything.

It would be great to be able to leverage listings outside of websites to generate tables, cards, grids, etc for single-page applications/reports without having to use R/Python. If it's not reasonable to add this feature to non-websites, it would be good to error/warn the user that it's not doing anything.

Minimal example - works on a website, but fails silently without the `_quarto.yml` file using Quarto: 0.9.600
