Support for the new command palette

[homer0]

Hi 👋 !

Before going to the issue... THANKS!! Your theme is amazing, and even after they released the official dark mode theme, I still prefer yours :D.

Now, during the last GitHub universe, they released the command palette, but it looks like it's broken with your theme: you don't see what you write.

I would be great to have support for it, as the palette is pretty useful.

Thanks.
