"Read about installing" link is broken on PPA pages

[DavidBriscoe]

PPA pages like this one:
https://code.launchpad.net/~ajmitch/+archive/unity-lenses

Have a section "Adding this PPA to your system" that has these instructions:
"You can update your system with unsupported packages from this untrusted PPA by adding ppa:ajmitch/unity-lenses to your system's Software Sources. (Read about installing)"

"Read about installing" is a link that points to:
https://code.launchpad.net/+help/soyuz/ppa-sources-list.html
But should be:
https://launchpad.net/+help/soyuz/ppa-sources-list.html
(Remove the code domain.)

The failing page is a valid link from the 'canonical' page for the archive - the code domain is whats wrong there, but the underlying problem is the bug I've duplicated this against. Thanks for the report!
