fix: respect ZSH's $ZDOTDIR environment variable (#942)

Browse Source 
ZSH reads its configuration by default relative to a path that's set via $ZDOTDIR. If $ZDOTDIR is not set, then the value of $HOME is used; this is the usual case. Source:  https://zsh.sourceforge.io/Intro/intro_3.html#IDX11

Also $HOME is save to use, because "The system shall initialize this variable at the time of login to be a pathname of the user's home directory". Source: https://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap08.html

Lastly, the shell parameter expansion syntax is save to use generically: https://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_06_02
