ComponentStore: Using ng add command fails with missing schematics error

[brandonroberts]

Minimal reproduction of the bug/regression with instructions:

1. Generate a new project
2. Run ng add @ngrx/component-store
3. Notice the error

The package that you are trying to add does not support schematics. You can try using a different version of the package or contact the package author to add ng-add support.

The schematics entry is missing from the package.json. An example can be found here https://github.com/ngrx/platform/blob/master/modules/store/package.json#L27

Expected behavior:

Versions of NgRx, Angular, Node, affected browser(s) and operating system(s):
