[#4] Fix error the $ZSH folder already exists

Dylan Wilson requested to merge issue-4 into main

Running the core states a second time gives the error the $ZSH folder already exists (/home/dylan/.oh-my-zsh) and causes the minion execution to hang (likely because it drops back into a Zsh session).

This is caused by the creates argument using ~ which refers to /root instead of /home/dylan. Replaced with an absolute value.

Closes #4 (closed).
