fix(version-info): explicitly specify the remote

`git ls-remote --tags` assumes that you have a remote set up for your
current branch.  That isn't the case, at least for me, when I'm working
on local branches.  `grunt write` doesn't do the right thing in that
case (`git ls-remote --tags` bails out and the silent: true param makes
this a pain to debug.)  Prefer explicit to implicit.
