Sync new tab wallpapers with system light/dark mode

So, really small one. If I’ve got my system dark mode enables (on Mac especially), Brave’s ‘chrome’ or UI automatically adapts to it. But the automatic Brave wallpapers don’t take this into account! So you get really bright, colourful pictures regardless of whether I’m trying to rest my weary eyes as I scroll through too many Reddit posts. Would love for this to be addressed.
