Remove ChessPursuit because it's non-free

[ghost]

There is a ChessPursuit game in Lichess 404 page. It's CC-BY-NC-SA so it must be removed to be free.

thanks, good catch. since it affects nothing but the 404 page and is trivial to remove, we'll just treat it like the other non-free artwork (although admittedly this one runs code). added to the list of things you need to check if you want to use lichess' code commercially: https://github.com/ornicar/lila/blob/master/COPYING.md via c77fad4

Why should "free" Lichess include non-free [anything]?

[niklasf]

before we argue this further let's just see if we can

• ask/convince @Saturnyn to release ChessPursuit under a free software license
• replace the minigame

i also opened #3509, which is going to be more difficult.

A temporary solution may be to create another branch and remove the currently non-free components.
