Manually update oh-my-zsh

When you're like me and running oh-my-zsh on mac in your iTerm console you won't get auto updates, because you just don't restart your console very often. There is a way to still get oh-my-zsh updates with running this command:

Old (Deprecated)

upgrade_oh_my_zsh

New Syntax

omz update
