git init --initial-branch (should docs mention v2 protocol)

Hi Maintainers,


Currently it is not obvious from the docs that (git init 
--initial-branch) needs v2 protocol setup on ssh server for (git clone) 
to work properly with unborn refs, as seen in this email thread

Should a link to the v2 protocol documentation be added in "git init 
--initial-branch" to make this configuration more obvious for admins/users?
