Show screenshots running on Windows

[JayFoxRox]

Currently, the website only shows macOS screenshots.
We should have at very least 1 Windows screenshot.
1 Linux screenshot would also be nice, although there's so few Linux users, that it's not too important.

The motivation is to attract Windows developers (which we clearly lack right now, despite being a large resource).

Though we've been pretty good about explicitly calling out platform support, I do agree that we should have some screenshots showing it actually working on Windows and GNU/Linux.

@Ernegien would you mind sharing some screen grabs from Windows?

Have a few Linux screenshots (tell me if the message is too long, I'll remove the previews):

Mechassault (quite good except for the menus, which I skipped by spamming A/start):

Fuzion Frenzy

A couple others that do not go ingame:

Slightly unrelated, but I also still own https://xqemu.imgur.com/ which has a lot of screenshots which we might want to move on a "Media" gallery on our ecosystem
