Add a link to the Nuclear Operative wiki page for nuclear agents

[Silvercloud29]

I don't fully disagree with this, but the issue is that. No nuke ops team is going to want to wait as like 1 or 2 guys are reading a full wiki page about how to play their class. There should be a decent in game write up that encourages the nuke ops to plan before rushing out to murder the crew.

Maybe consider adding weights to the antag selection system (if possible) to make the nuke ops leader someone who's an experienced player or mentor?
