Tweak source code modal for large screens

I suggest to make source code modal wider on large screens to avoid word wrapping.

Bootstrap 5 has [.modal-xl](https://getbootstrap.com/docs/5.1/components/modal/#optional-sizes) CSS class for this. But we use Bootstrap 3, so I just created a "polyfill" for that feature.
