Jonas Jenwald ae1cbc6a9e Use the light-dark CSS function in the viewer (issue 17780)
This removes the need for (most) separate `@media (prefers-color-scheme: dark)` blocks when defining colors values, and also provides a simple way of forcing use of either the light or dark theme.

Please refer to https://developer.mozilla.org/en-US/docs/Web/CSS/color_value/light-dark and https://developer.mozilla.org/en-US/docs/Web/CSS/color-scheme

*NOTE:* To support this in older browsers, we utilize a [PostCSS plugin](https://github.com/csstools/postcss-plugins/tree/main/plugins/postcss-light-dark-function).
