use @msw/data instead of manual factories

[taneba]

As @kettanaito commented on my article about msw, @msw/data seems pretty nice in terms of reducing boilerplates.

Would like to tackle on this after model generics is supported because we have already type defs for our models.
see: mswjs/data#36

Hey, @taneba! Don't hesitate to contribute with the factory generics support, I'm sure we could use your expertise. I'd be happy to help you with the code review and making this support happen.

Hey there, @kettanaito
Yeah I'd like to give it a try, (that's why I forked the repo) I'll take a closer look when I have time :)
