Docs App: current version is not selected in version picker in specific versions

[Narretz]

Repro:

1. Go to https://docs.angularjs.org/api. The version picker will show "master"
2. Select any of 1.5.10, 1.5.11, 1.6.0-rc.1, 1.6.0-rc.2, 1.6.0-rc.3, 1.6.0, 1.6.1, 1.6.2
3. The version is not selected in the new page

Probably related to changes we made to the storage of the current / all version data. cc / @petebacondarwin

So in the all-versions-data.js file, the current version is missing. Thes available version are those that are in the yarn registry.
The current version is available in the current-version-data.js file, though, which is retrieved locally.

These files are generated here: /docs/config/processors/versions-data.js

I wonder if this is because at the point when this script runs, the new version hasn't actually been published / pushed to yarn yet?
