git-sh-setup: remove unused "pull with rebase" message

Remove the "pull with rebase" message previously used by the
git-pull.sh script, which was removed in 49eb8d3 (Remove
contrib/examples/*, 2018-03-25).

Even if some out-of-tree user copy/pasted the old git-pull.sh code,
and relied on passing it a "pull with rebase" argument, we'll fall
back on the "*" case here, they just won't get the "pull with rebase"
part of their message translated.

I don't think it's likely that anyone out-of-tree relied on that, but
I'm being conservative here per the discussion that can be found
upthread of [1].
