refactor(sidenav): remove deprecated access to $media in md-is-locked-open

- improved layout and position of `$mdMedia` docs section in Sidenav API docs

BREAKING CHANGE: Removed access for the deprecated `$media` service in `md-is-locked-open`. This was deprecated in favor of the `$mdMedia` service. The functionality is the same and only a rename to the current name of the service is required.
