docs(changelog): drop reverted self-host onboarding beacon from v0.3.32

The anonymous self-host onboarding source beacon (MUL-3708, #4691) was reverted in #4712 because of issues with the collection path. Remove the corresponding feature bullet from all four locales so the v0.3.32 changelog only advertises what actually ships.
