Arbitrary `include` is allowed by type checking even when the model has no relation field.

[jiashengguo]

model Dummy {
    id   Int    @id @default(autoincrement())
    name String
}

Then the below query code could pass the typechecking, and runtime will throw error:

  const dummies = await db.dummy.findMany({
    include: {
      abcdefg: true,
    },
  });

For this case it's better to not allow to use include at all, which is consistent with v2 behavior
