l1_reg="auto" is deprecated (in SHAP)

[frycast]

When running the following example from the shapper regression vignette on CRAN:

library("shapper") ive_rf <- shap(exp_rf, new_observation = new_passanger) ive_rf

We get a warning from the SHAP package:

l1_reg="auto" is deprecated (in SHAP) and in the next version (v0.29) the behavior will change from a conditional use of AIC to simply "num_features(10)"!
