Use hyperparams from `rf` for `parRF`

[kelly-sovacool]

parRF is just a parallel version implemented by caret using the same underlying package as rf, so we can use the same default hyperparameters for both.

Error in get_hyperparams_list(dataset, method) : 
  method 'parRF' is not supported.

In addition: Warning message:
In check_method(method) :
  Method 'parRF' is not officially supported by mikropml. However, this method might work in our pipeline. You can use the caret documentation to see what hyperparameters are required. Supported methods are:
    glmnet, svmRadial, rpart2, rf, xgbTree
