This is not the correct location to fix this, it's here:

diff --git a/git-completion.zsh b/git-completion.zsh
index 0ef15ff..df98e68 100644

Commit 59d85a2a05 (git-completion.bash: use $__git_cmd_idx in more
places, 2021-04-22) broke zsh because it modified __git_main, but not
__git_zsh_main.

Cheers.
