chore(package): Fix typo in package.json

[NickTomlin]

Closes #22

This updates the repository field using the shorthand in the npm docs.

@qiyigg if this looks good do you have a moment to walk me through the release process? I've never published this package (or feel free to do it yourself if you'd rather handle all the releases 😄).

[qiyigg]

My understanding is this repo is not actively maintained by Angular team. Last time I did a release was only for Protractor release which also solved the security issue in Angular CLI. And I just "npm publish" it....

[NickTomlin]

Ah interesting. I don't actually think I have the ability to publish this myself.

If this is deprecated do we plan to remove it from protractor? Or perhaps transfer it to a community maintainer?

[qiyigg]

We don't actually know how many users use this repo through Protractor or use it directly.
I cannot tell we could deprecate it or not and we don't have this kind of plan yet. As long as Protractor still reply on it, Angular team has to reserve the rights to release. Actually before I release the latest version, this repo had been silent for a long time ... anyway, if there's some new good feature or serious bug fix, I can help to do the release; otherwise, I'd like just keep as it is right now.
