go/doc: use correct escaper for URL

Browse Source 
Despite the name, URL escaping is for a small subpiece of the URL only.
This particular URL is being emitted in an <a href=""> tag and in that
context it should be HTML escaped, not URL escaped.

In addition to fixing a bug, this change cuts a dependency chain
from go/doc to net, clearing the way for use of cgo
(which imports go/doc) during the compilation of package net.
