What did you expect to see?

This feature is supported in both Chrome 150 and Firefox 150.

Did you test this? If so, how?

Manual check to find light-dark in css.types.image, which is not present. This in parallel to css.types.color.light-dark which is present.

Can you link to any release notes, bugs, pull requests, or MDN pages related to this?

Checking css.types.color, I see that light-dark has a subkey image … which is weird as an image is not a color.

css.types.image.light-dark was the place I intuitively expected it to be at, so perhaps this should be moved?
