implement missing nested `set` operation

[schoero]

Prisma has a nested set operation to connect the provided relations while disconnecting previous ones.

It is not very well documented, the only reference I found apart from the type definitions is this: https://www.prisma.io/docs/orm/prisma-client/queries/relation-queries#disconnect-all-related-records

Disconnect all related records

To disconnect all related records in a one-to-many relation > (a user has many posts), set the relation to an empty list as shown:

const result = await prisma.user.update({
  where: {
    id: 16,
  },
  data: {
    posts: {
      set: [],
    },
  },
  include: {
    posts: true,
  },
})

The library is currently missing the nested set operation.
