What is the current behavior?

Currently Update type for type checking updateMany and updateOne methods of entity adapter is only available in deep import import {Update} from '@ngrx/entity/src/models'

Expected behavior:

It should be provided as top level import

      import {Update} from '@ngrx/entity';

      // ...
      const updates: Update[] = action.payload.map(item => ({id: item.unixTime, changes: item}));
      return {
        ...adapter.updateMany(updates, state),
        loading: false,
        loaded: true,
        errorMess: null,
      };

Minimal reproduction of the problem with instructions:

Version of affected browser(s),operating system(s), npm, node and ngrx:

I think this #675 should release a version if docs is updated.
