chore: bump version to 0.3.2 (#1909)

* chore: bump version to 0.3.2

* fix: correct changelog generation — use tag sort instead of git describe, remove duplicate entries

- Replace git describe --tags --abbrev=0 with git tag --sort=-version:refname
  to find the correct previous tag (git describe misses tags on unmerged
  release branches)
- Change changelog section heading from '### Changed' to '### Changes'
- Remove duplicate entries from 0.3.2 that belonged to prior releases
- Clean up changelog preamble and stale entries
