Add the instance:
```lean
instance {ι : Type _} [Countable R] [Countable ι] (v : ι → M) : Countable (Submodule.span R (Set.range v))
```
which is needed to be able to apply Minkowski theorem to ℤ-lattices. This instance, in turn, uses the new instance:
```lean
instance [Countable α] [Countable M] : Countable (α →₀ M)
```
