Please include removal of density_auto function in minor changes log for 3.3.2

[marknwarden]

Old code I wrote that used ggdist crashed unexpectedly with a mysterious error saying density_auto not found. Upon searching the commit logs, I noticed that updating from 3.3.1 to 3.3.2 removed density_auto from ggdist entirely in favor of density_bounded. Please update documentation (change log) to include this change as it is not currently documented.
