Models documentation header mismatch

[marcelglueck]

The problem

It seems that the header for quite some neural network models does not fit their content:

Example:

• https://parsnip.tidymodels.org//reference/details_mlp_keras.html: Header says "Multilayer perceptron", but the document says otherwise ("keras_mlp() fits a single layer...")

The same applies to https://parsnip.tidymodels.org//reference/details_mlp_nnet.html. Please correct me if I am wrong.
