Add Apple to list of providers. (#323)

* user_management: add Apple to list of providers.

This may be me completely understanding this code but: this looked like an omission here so I thought I'd open a PR for discussion.

* types/provider: add another missing Apple addition.

* Fix specs

* Fix Rubocop offense
