V0.6: Linux Build!

Hello :)

A quick patch to make the game available on Linux, I use GLFW as an abstraction layer and use GitHub actions to build, I don't use Linux myself so I have no idea if it runs without issues.

Please let me know if you try and it doesn't work, there should be an error log here: ~/.local/share/Orbis/logs/Orbis.log

Edit: Not very surprinsigly, the first Linux build was not working, so I released a patch to fix it (0.6.1)
