Issue for codesmell in backend works/:id/reviews and reviews/board/

[hursuhyun]

works/:id/reviews 와reviews/board/(그 외 더 많은 부분이 존재할 수 있음)에서 foreign_key로 object를 가져오는게 안 되어서 일일이 값을 넣어주어야 하는데 이 부분을 통합하면 좋을 것 같습니다.

    for review in board_reviews:
        work = review.work
        work_artist_name = [artist.name for artist in work.artists.all()]

        work_dict = {
            "id": work.id, "title": work.title, "thumbnail_picture": work.thumbnail_picture,
            "platform_id": work.platform_id, "year": work.year, "artists": work_artist_name
        }

        author = User.objects.get(id=review.author_id)
        author_dict = {
            "id": author.id, "username": author.username, "email": author.email, # "profile_picture": author.profile_picture
        }
        response_dict.append({
            "id": review.id, "title": review.title, "content": review.content, "score": review.score, "likes": review.likes,
            "work": work_dict, "author": author_dict
        })
