Example case in documentation is using deprecated features

[hxtmike]

When I ran the example code in GGally documentation, the console show this warning message to me. It seems that you are using a deprecated feature in ggplot2

ggally_facetdensitystrip(tips, aes(x = total_bill, y = day))
#> Warning message:
#> The dot-dot notation (`..scaled..`) was deprecated in ggplot2 3.4.0.
#>ℹ Please use `after_stat(scaled)` instead.
#>ℹ The deprecated feature was likely used in the GGally package.
#>  Please report the issue at <https://github.com/ggobi/ggally/issues>.
#> This warning is displayed once every 8 hours.
#> Call `lifecycle::last_lifecycle_warnings()` to see where this warning was generated.
