contrib/completion: fix zsh completion regression

Despite 0b18023 addressing a regression from 59d85a2, the issue described in [1] still persists as described:

compdef _git ga=git-add
ga <tab>
ga __git_find_on_cmdline:[:16: unknown condition: -lt

The suggested fix to set __git_cmd_idx for the _git function wrapper worked for me on:

- zsh v5.8.1
- git v2.40.1
