Update package-lock.json

We need to update package-lock.json to use sha512 algorithm for
integrity checksum in order to get rid of the following warnings:

Please note, the following warnings are shown when you run `npm install`
from scratch (i.e. no dependencies are installed). You probably will
need to run `npm cache clear --force` on your machine before.
