doc: drop scheme from links that are known to support HTTPS

golang.org now serves HTTPS with a valid cert, so it's reasonable
that users should click through to the HTTPS versions of *.golang.org
and other known sites.

 One of Go's key design goals is code adaptability; that it should be easy to take a simple design and build upon it in a clean and natural way. In this talk Andrew Gerrand describes a simple "chat roulette" server that matches pairs of incoming TCP connections, and then use Go's concurrency mechanisms, interfaces, and standard library to extend it with a web interface and other features. While the function of the program changes dramatically, Go's flexibility preserves the original design as it grows.
