Support for "earth" models

[mdancho84]

Getting this error when trying several tidymodels: MARS (shown), Random Forest, etc

Error in if (minfo$is_bayesian) { : argument is of length zero

Reproducible Example

# * MARS Regression ----
library(tidymodels)
library(tidyverse)
library(performance)

model_earth_tidy <- mars(mode = "regression") %>%
    set_engine("earth") %>%
    fit(hwy ~ displ + class, data = mpg)

check_model(model_earth_tidy)
#> Error in if (minfo$is_bayesian) {: argument is of length zero

In your example, a model of class earth is fit, which is not yet supported. I'm moving this issue to the relevant repository.
