spec: better comment in example for type definition

The old comment for the example

	type PtrMutex *Mutex

talked about the method set of the base type of PtrMutex.
It's more direct and clearer to talk about the underlying
type of PtrMutex for this specific example.
Also removed link inside pre-formatted region of text.

Fixes #20900.
