Adds new space ruin content and changes how space ruin away roles works (#8058)

This pr adds a new cool space ruin made by kyres, replacing the listening outpost and the sol corvette, that were lame. This space ruin has two ghost roles.

This pr also makes so that space ruin sites only open if the research shuttle is launched to an away site, they will be closed otherwise. The research shuttle also has a transit time and area now.
