Inconsistent axes in cal_plot_logistic()

Problem

cal_plot_logistic has a different y-axis labels from cal_plot_windowed or cal_plot_breaks. Consistency ("Event Rate" for cal_plot_logistic would be nice).

The current version ("Predicted Event Rate") is confusing to me. I thought the y-axis was the 'truth' and the x-axes in these graphs were derived from model predictions.

Reproducible Example

library(ggplot2)
library(dplyr)
#> 
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':
#> 
#>     filter, lag
#> The following objects are masked from 'package:base':
#> 
#>     intersect, setdiff, setequal, union
library(probably)
#> 
#> Attaching package: 'probably'
#> The following objects are masked from 'package:base':
#> 
#>     as.factor, as.ordered
cal_plot_logistic(
  segment_logistic,
  Class,
  .pred_good
)

cal_plot_windowed(
  segment_logistic,
  Class,
  .pred_good,
  window_size = 0.05
)

cal_plot_breaks(
  segment_logistic,
  Class,
  .pred_good,
  window_size = 0.05
)

Start at the cal_plot_logistic() entry point and compare its axis labeling with cal_plot_windowed() and cal_plot_breaks(). Re-run the three examples from the issue to inspect the labels. Done means cal_plot_logistic() uses the consistent “Event Rate” y-axis label without changing the other plot behavior.
