Use GitHub dependency instead of own registry

[GittiHab]

Hello there,
is there a special reason that you recommend installing graph-app-kit via your own registry? This makes it harder building apps that depend on it, i.e. specify it in their package.json.

As far as I understand this shouldn't make a difference. In this case I would propose also adding an example for usage as an dependency in the package.json in the readme-file:

"graph-app-kit": "neo4j-apps/graph-app-kit#1.0.0"
