The default end tag was determined by listing all tags and filtering out prereleases. As a result the currently built
prerelease tag was never evaluated and the changelog was generated for the previous stable release instead. The end tag
is now the tag of the checked out commit, so the prerelease annotation is set as expected. Prerelease filtering remains
in place for the start tag only. Additionally the changelog is no longer skipped for prereleases, since consumers of the
chart benefit from the changes list before the stable release.
