Subject: [PATCH] Adjust instruction for setting custom $ZDOTDIR

Adjust instruction for setting custom `$ZDOTDIR`.

This addresses 2 potential issues:
- Check for the presence of `$XDG_CONFIG_HOME/zsh` before assigning it to `$ZDOTDIR` instead of blindly assigning
- Avoid recursion in zsh variable assignment stack that might occasionally result in messages like:
```
zsh: job table full or recursion limit exceeded
```
