Crtrl-r no longer working out of the box

[jessieay]

Hello!

Over the last few weeks, a noticed that ctrl-r was no longe working for fuzzy finding.

I just found this comment in the fzf repo and the solution worked: junegunn/fzf#4261 (comment)

Could we add this to the zshrc in the dotfiles so crtl-r works out of the box once again?
