adding light documentation to security.yml

Hi guys!

When we removed AcmeDemoBundle recently, we lost a lot of "example" security configuration that was there before. I realized this in a training - you open this file, but don't know where to go next. I've added some very basic links to help get the user moving.

@javiereguiluz does this make sense to you?

Thanks!
