**args in custom metric

[ohenry-proda]

In
https://microsoft.github.io/FLAML/docs/Use-Cases/Task-Oriented-AutoML#optimization-metric
the inputs of the example function are as follows:

def custom_metric(
    X_val, y_val, estimator, labels,
    X_train, y_train, weight_val=None, weight_train=None,
    **args,
):

Should this be *args?

It seems this was discussed at #477 but the docs were never changed, if I'm not mistaken

Thanks for your suggestion! We have made a PR to fix this mistake in the docs. #883.
