The Problem

Discord just revamped their UI (again). With this comes a few new background colors:

These should be added to colour.py.

I don't have time to look at it now, but if I have the chance I'll grab the colors and add them to the list

The Ideal Solution

Add the colors to colour.py

I would recommend that the colors be called ui_light, ui_ash, ui_dark, and ui_onyx?

Discord.py has historically kept classmethods on discord.Color/Colour that refer to Discord branding colours, think of the default role colours, etc.
Lately this also includes a wider array of them.

This PR would simply add the dominant background colour of the new themes. It's just shortcut methods to access those colours for things like embeds.

@rrbailey89 this wouldn't affect a bot, this issue is just asking for new colour constants to be added to the discord.Colour class, so they can be used to colour the border of an embed, or anything else using this class.

See #10152 for an implementation.
