Modules should show parent link

[toddjordan]

Modules show a link to the parent module (usually ember)

[MartinMalinda]

It is fetched from @module
https://github.com/emberjs/website/blob/master/source/api/module.html.erb#L6

Which is provided by YUIDoc output:
https://github.com/emberjs/website/blob/master/data/api.yml#L1635

ember-jsonapi-docs do not expose this value yet:

Some parentModule relationship will probably be needed.
