Bug when mo-doc generating docs for public var.

[AStepanov25]

This code:

module {
  public class Class() {
    /// Docs
    public var a : Nat = 0;
  };
};

when being run with this command:

$(dfx cache show)/mo-doc --format plain

causes this output:

Failed to extract documentation for declaration:
(VarD a (AnnotE (LitE (PreLit 0 Nat)) (PathT (IdH Nat))))

and no doc for public variable in md file.
