In order to support automatically updating the release notes when we
create stable branches, we want the pages to be in a standard order.
This patch updates the order to be reverse chronological, so the most
recent notes appear at the top.

We need a release notes page to show notes for unreleased versions by
scanning the "current" branch. This ensures that notes files cannot be
merged if they break the releasenotes job.
