It seems that the release drafter filters commits which have been made
before the last release has been made. If the last release is a
unrelated stable release, this clears the full changelog for the next
major release. It seems `filter-by-commitish` should prevent that.
While at it, also set `commitish` to be dev (which is the default, but
being explicit certainly doesn't hurt).
* Change titels to reflect official/new naming
* Use GitHub Actions to trigger Release Drafter
The Add-On is no longer developed and GitHub Actions is the recommended
way to use the Release Drafter
