Ensure shorthand "repository" in package.json when GitHub repo

[sindresorhus]

sindresorhus/np and not the following:

• https://github.com/sindresorhus/np.git
• https://github.com/sindresorhus/np
• {"type": "git", "url": "https://github.com/sindresorhus/np.git"}
• {"type": "git", "url": "https://github.com/sindresorhus/np"}

This only applies when it's GitHub right? If it's BitBucket, it should be the full url?

Yes
