fix: mlx: Wrong type annotation for latent_size

Pyright: Argument of type "tuple[Literal[64], Literal[64]]" cannot be assigned to parameter "latent_size" of type "Tuple[int]" in function "generate_image"
  "tuple[Literal[64], Literal[64]]" is not assignable to "Tuple[int]"
    Tuple size mismatch; expected 1 but received 2
