Commit messages in releases repo has incorrect version number for RC releases #15

https://github.com/yarnpkg/releases/commits/gh-pages
There's a bunch of "Automated upgrade to Yarn 0.24.6" commits. In fact, only one of these is 0.24.6, all the others are newer RC versions
The issue is that update-and-push.sh always includes the latest stable version number in the commit message, even when an RC is being added: https://github.com/yarnpkg/releases/blob/gh-pages/update-and-push.sh#L13,L15
