chore(release): stamp 0.4.0 / 0.1.1 / 0.2.0 changelog headings

The three versions the Release Please manifest asserts are released are being
tagged as this branch merges, so their notes move out of `## [Unreleased]` and
under a dated version heading. No fresh `## [Unreleased]` section is added:
under Release Please the open release PR for a chart is the pending version.
