x/website: "The Laws of Reflection" blog post needs a section on generics

[griesemer]

The blog post The Laws of Reflection, while old, is still a commonly used in-depth resource for the reflect package. There needs to be a preamble explaining how the reflect package is affected by generics (it isn't).

I would say rather than a preamble, it just needs a clarification in a couple of places. It also needs a tweak because Println etc. now handle reflect.Type more nicely, which invalidates a tiny bit of explanation.
