Wrong label for the figure 15.3

[lionelkusch]

The label of y-axis of the right figure 15.3 is : lift\max_lift
My interpretation is that the value should be 0 and 1. It's not the case.
I assume that the label is wrong or that the division by 0.3222 is not good.

	pl2 <- plot(model_performance(explain_rf), geom = "lift") +
	geom_line(aes(pr, lift/0.3222), size=1.4, color = "#371ea3") + theme(legend.position = "none") + theme_ema + ylim(1,3.13)
