ls-remote doc: document the output format

While well-established, the output format of ls-remote was not actually documented. This patch adds an OUTPUT section to the documentation following the format of git-show-ref.txt (which has similar semantics). Add a basic example immediately after this to solidify the 'normal' output format. Signed-off-by: Sean Allred <allred.sean@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

108 +When showing an annotated tag, unless `--refs` is given, two such

110 +and another with `<ref>` followed by `^{}`. The `<oid>` on the latter
111 +line shows the name of the object the tag points at.
