Drop deprecated URL for introduction from BYU

https://docs.cs.byu.edu/ is still around, though http://docs.cs.byu.edu/linux/advanced/zsh.html no longer exists since around 2011 (see http://web.archive.org/web/20110718200750/http://docs.cs.byu.edu/linux/advanced/zsh.html). Thanks: Christopher Bock for the hint
