Since h2o uses different values for activation functions, we can
take the values that are consistent with current tidymodels engines (e.g. "tanh") and translate them inside of h2o_train_mlp() to be what h2o expects (e.g. "Tanh").
Also, we could expand what dials has as possible values to include others in h2o that tidymodels does not currently have (or just fail if the value is not in our current list).
