DeepPartial update breaks Active Record create/merge

[bellstrand]

Issue Description

#8817 partially broke create & merge functions in Active Record setups by.

Expected Behavior

I'd expect a Active Record entities create & merge functions to be able to take a valid limited input as a parameter.

Actual Behavior

fails to compile because of

No overload matches this call.
  Overload 1 of 3, '(this: (new () => Item) & typeof BaseEntity, entityLikeArray: DeepPartial<Item>[]): Item[]', gave the following error.
    Argument of type 'Pick<Item, "value">' is not assignable to parameter of type 'DeepPartial<Item>[]'.
      Type 'Pick<Item, "value">' is missing the following properties from type 'DeepPartial<Item>[]': length, pop, push, concat, and 26 more.
  Overload 2 of 3, '(this: (new () => BaseEntity) & typeof BaseEntity, entityLike: DeepPartial<BaseEntity>): BaseEntity', gave the following error.
    Argument of type 'Pick<Item, "value">' is not assignable to parameter of type 'DeepPartial<BaseEntity>'.ts(2769)
BaseEntity.ts(185, 12): The call would have succeeded against this implementation, but implementation signatures of overloads are not externally visible.

Steps to Reproduce

1. Copy & paste snippet

@Entity()
export class Item extends BaseEntity {
    @PrimaryColumn()
    id: string
    @Column()
    value: number
}

const input: Pick<Item, "value"> = { value: 42 }
const item = Item.create(input)
