Make reference to ".repo" alias

It seems that the Component team often use this alias (e.g. [tap](https://github.com/component/tap/blob/576b92dbdc110f45dff693951c9184107344f9d5/component.json#L3), [assert](https://github.com/component/assert/blob/c636e751f22199f2ef454d7a3ce36218799375eb/component.json#L3), and [reactive](https://github.com/component/reactive/blob/17b35a3de774d657205a9ec6bca53be92cd1ed78/component.json#L3)).
