A user's shell config might destructively alter the shell's $PATH (also
common on MacOS, which destructively sets $PATH with its system dotfiles
for ZSH). This prevents the sub-shell spawned from `doom/reload` and
`doom/upgrade` from inheriting emacs' `$PATH`, which Doom adds
$EMACSDIR/bin to. Without this entry, these commands would fail to find
the Doom script.
