please fixed merge conflict issue in package.json

I like your article you made about this topic, however, one of my biggest pet peeves is someone explaining something but has code in their article and they don't at least show what import it comes from. How can anyone follow your article if they don't know what diskStorage is without coming to the github and looking into it themselves?

I think you missed to extends Document in item.interface.ts you did it in your article about graphQL.

To better describe my problem: By following the instruction on crash course nest I get the type errors that in items.service.ts save is not defined with I think is related that the Type Item doesn't contain all the logic from mongoose.

Both Blog posts are well written. It's fun to follow them and to get a first view into Nest.

It would be nice if you can update the tutorial to actually match the files provided, missing @ObjectType for example will eventually make the nestjs app to never work correctly.
