Please add a config to revert the changes to the light buttons

I like a lot of what V9 changes, but the changes to how light buttons work is not my thing. I prefer the old look!

Thanks! The v8CssVariablesResolver is working great. Is this a temporary measure? Will the resolver keep working in versions 10, 11, etc? What would be the path to be able to preserver the v8 colors in future versions?
