Remove purpziesucks and change purpzie

Moved purpzie.github.io to purpzie.github.io/site. Because purpzie.github.io redirects to purpzie.js.org right now, it won't show https://github.com/purpzie/site but you can still check the files, they have content.
I was the one who put these in originally (https://github.com/js-org/js.org/pull/1970)
