Fix CHANGELOG entries for v0.10.6 and v0.11.0

Both release entries have minor issues:

- v0.10.6 notes Alpine image updates which were intended
  to be provided in this release, but were not
- v0.11.0 omits Go version bump, new images
  - addition of `oldstable` Alpine images
  - update of Alpine version, Go version
