[Feature Request] Catppuccin theme

Hi, it's me again :) I noticed there are a lot of themes to choose from. But arguably one of the most popular ones is missing: Catppuccin. Could you perhaps take a look at whether it's possible to add the Catppuccin theme? Personally I'm a big fan of the Mocha flavor, with the blue accent color. But I'd be happy with anything Catppuccin.
