Support dark mode for builtin themes

It doesn't look like any/most of the provided themes support dark mode. That's a real bummer since many similar generator themes like the default MkDocs theme does support dark mode.

Happy to accept contributions to add dark mode or otherwise improve our themes!

Hi! I’m a GSSoC’25 contributor and would love to work on adding dark mode support to the built-in themes. Kindly assign this to me. 😊

That would be great! I'm most interested in the Haiku theme, that's what LLVM uses for its docs. Most of that comes from the basic theme it looks like.
