[DOC] Missing parenthesis in docstring of MASE

[caph1993]

There is a missing parenthesis in the documentation of the function MASE.

Current: (y_pred - target).abs() /  all_targets[:, :-1] - all_targets[:, 1:]).mean(1)
                                   ^
                                   |
                                   v
Correct: (y_pred - target).abs() / (all_targets[:, :-1] - all_targets[:, 1:]).mean(1)
