Comment out storybook-deploy step

The Storybook deploy step is currently broken because it's using the
wrong source branch (`master` instead of `develop`), and because the
key that CircleCI is setup with doesn't have write access to the repo.

While I expect we'll get these two problems fixed soon, this ensures
that we at least have passing builds on `develop` in the meantime.
