Fixing $PATH changes in tmux

I noticed that my $PATH was being set differently between tmux and a regular shell. Specifically, without tmux my Ruby installation from asdf would override the default one but in tmux it would not.

Eventually, I was tipped off by this blog post that the issue might be my /etc/zprofile file, and that was indeed the case; changing the code to this fixed it for me:

if [ -x /usr/libexec/path_helper ]; then
	PATH=""
	eval `/usr/libexec/path_helper -s`
fi

Now, the directories that I want on the front of $PATH are consistently placed there.
