Is your feature request related to a problem? Please describe.
Ladle currently has theme add-on that supports white and dark background, I think it would be useful for this add-on to also support "light gray" background for the following reasons
It somewhat common, eg admin interfaces/dashboards, trello like dashboards
The current white and black background does not work particularly well for components that are made for these gray backgrounds (eg some box with white background and shadow)
Describe the solution you'd like
Extending the theme add-on to allow for more than 2 backgrounds, maybe with similar approach as the viewport addon, where you have popup with list of options inputs
Having a way for story to define default background
Describe alternatives you've considered
The most obvious alternative is using the already existing story decorators, where you would add some kind of layout wrapper component that just changes the background, but this use-case seems common enough that it might be nice to have it included out of the box
