License information format in package json is deprecated

[ankitbharadwaj]

the license format in package.json needs an update so that it can be picked up by the npmjs or the snyk scans.
New requirement is something like this
{
"name": "name",
"version": "1.0.0",
"license": "MIT"
} instead of what is there as of now

"licenses": [
{
"type": "MIT",
"url": "http://github.com/Raynos/dom-walk/raw/master/LICENSE"
}
],
