Option "projects" in configuration file does not work

[tobernguyen]

Do you want to request a feature or report a bug?: Bug

What is the current behavior?: Jest won't run when I include projects option in the configuration file and pass an array of Object into that. Just like the example in docs: https://facebook.github.io/jest/docs/en/configuration.html#projects-array-string-projectconfig

{
  "projects": [
    {
      "displayName": "test"
    }
  ]
}

Returned with error:

TypeError: glob pattern string required

Reproduce: https://repl.it/repls/ImpeccablePortlyDiscus

What is the expected behavior?: It should able to load projects with different setting for each project.

Please provide your exact Jest configuration and mention your Jest, node,
yarn/npm version and operating system.:
yarn: v1.0.2
npm 5.3.0
node: v8.6.0
OS: OS X 10.12.6

This feature is not yet released, see #5176 and Changelog: https://github.com/facebook/jest/blob/master/CHANGELOG.md

We should probably update the docs stating that it's not released yet (I want #5190 really bad, so much confusion around it)

I hope it get released soon 😸
And, I think it's kinda misleading to state a non-released feature in the doc tho 😅

It has been released now, though
