chore(tools): update packaging changelogs in bump-version.ps1 (#1205)

`tools/bump-version.ps1` will now update the packaging changelogs as
well. The only thing it does is adding a new section for the new
version, stating that no change was made to the package itself. If
something was changed, the files should be modified manually afterwards.
