Fix Apache-2.0 licensing in package.json

[hobie2987]

grunt-env/package.json

Lines 18 to 22 in 27ad077

	"licenses": [
	{
	"type": "Apache2",
	"url": "https://github.com/jsoverson/grunt-env/blob/master/LICENSE-Apache2"
	}

It appears the Apache 2.0 licensing in the package.json is old, and should be updated to use the following values:

type: "Apache-2.0"
url: "https://www.apache.org/licenses/LICENSE-2.0" or "http://www.opensource.org/licenses/Apache-2.0"
