Prevent expansion in some lines in .zi-create func

[Farzat07]

This makes sure that the lines output to the PLUGIN_NAME.plugin.zsh file are as intented in the documentation:
https://wiki.zshell.dev/community/zsh_plugin_standard#zero-handling

I just had the feeling that the variable expansion in these two particular lines wasn't intentional.

What is the current behavior?

The following lines are created as a part of the file PLUGIN_NAME.plugin.zsh:

0=".zi-create"
0="MY_ZSH_HOME/.zi/plugins/_local---my-zsh-completions/.zi-create"

What is the new behavior?

The following lines are created instead:

0="${ZERO:-${${0:#$ZSH_ARGZERO}:-${(%):-%N}}}"
0="${${(M)0:#/*}:-$PWD/$0}"

Does this introduce a breaking change?

• Yes
