Fix the pyperformance Repo URL. (#664)

ericsnowcurrently · web-flow · commit 9a10a2d5a208 · 2021-03-19T12:00:10.000-06:00
The repo changed name, from "performance" to "pyperformance", a while back.  The devguide did not get updated at that time.  Updating the links here means GitHub will no longer need to rewrite the old URL in requests.
