examples/README: Add a pointer to the releng Git repository

Thanks to Dustin C. Hatch for pointing this out, because I wasn't able
to find it on my own.  Having a pointer distributed with Catalyst
should help other newcomers find example spec files written by folks
who know what they're doing ;).  The current examples lack a full
stage1-through-stage3 progression.
