godoc: add alt attr to gopher on main package index
The gopher with a miner hat on /pkg had no alt attribute
so screen readers would announce the image by its filename.
As the image is purely decorative, adding the empty string
as alternative text prevents the image from being announced.
For golang/go#22171
