Cannot assign entities to Relation annotated properties.

[stringthread]

Describe the bug

Type 'Item' is not assignable to type 'Relation<Item>'

Minimal reproducible example

@Entity()
class Item {
  id: number;
}

@Entity()
class List {
  id: number;

  @ManyToMany()
  items: Relation<Item>[];
}

const list = new List();
const item = new Item();
list.items = [item]; // ERROR

Expected behavior

It should be possible to assign entities into properties.
