What's the rule?  Why is zsh-users/zsh-completion there and
seebi/dircolors-solarized not?

I'm guessing you want:
.
    plugin_paths+=( */*/.git(N:h) )

or:
.
    typeset -aU plugin_paths
    plugin_paths+=( */*/*.plugin.zsh(N:h) )

Explanation: */*/.git expands to the names of all directories named foo/bar/.git.
If there are none, it will append nothing, because of the (N) qualifier
(otherwise an error would have been raised).  The (:h) qualifier drops the last
path component, leaving just foo/bar.  The second solution is similar, but
uses the -U flag to make the array unique, in case the glob has more than
one match in a single directory.
