A typo in multinom_reg() documentation?

[hnagaty]

I'm wondering if stan is valid engine when using parsnip::multinom_reg() or not?
In the documentation at Multinomial regression — multinom_reg • parsnip, it is mentioned that stan is a valid engine in the "Details" section.
When I tried to use a stan engine in multinom_reg(), I got an error message "Error: Engine 'stan' is not available. Please use one of: 'glmnet', 'spark', 'keras', 'nnet'".
