Don't use GitHub URLs in auto-generated code

[cgay]

This is the default (for me) dylan-package.json file. It shouldn't assume use of GitHub, especially given all the GitHub backlash happening these days.

{
    "dependencies": [  ],
    "dev-dependencies": [ "testworks" ],
    "description": "YOUR DESCRIPTION HERE",
    "name": "hello-world",
    "version": "0.1.0",
    "url": "https://github.com/cgay/hello-world",
    "keywords": [ ],
    "contact": "https://github.com/cgay/hello-world/issues",
    "license": "",
    "license-url": ""
}

Maybe put something like *** REQUIRED FIELD *** (URL, email, etc) for "contact" etc
