Add uwu=true easter egg

[Morganamilo]

A while ago twitter user starting creating cute logos for a bunch of tech related projects. This quickly became very popular and sites started adding this as an easter egg.

This patch does the same for the archlinux website. Adding ?uwu=true to the url will replace the normal logo with a cute version.

I've already contacted the artist (https://x.com/sawaratsuki1004) and gotten permission to use the image here.

Some examples of sites that have already implemented this:

https://www.haskell.org/?uwu=true https://qwik.dev/?uwu=true https://react.dev/?uwu=true https://nextjs.org/?uwu=true https://vite.dev/?uwu=true https://angular.dev/?uwu=true

These are just the ones I know of, there's many more out there but there's no defined list.

I think we need some written proof, or them to license it CC0 somewhere public.

As for the change, the uwu logo doesn't fit in the navbar anymore and it looks a bit weird.

Yeah I had to move it about because it was too detailed for it to really be visible in the normal position. It looks ' bit silly but that's the point imo

I have a consent email attached Permission to Use Kawaii Logo.eml here. Hopefully you think it's still mergable even if it looks a bit funky.

I also would like it to fit in the nav bar
