We need a privileged / admin user doing the post-release version bump as
this is a direct commit to main (i.e. without a PR) so switch to using
schutzbot with a scoped personal access token (only public_repo).
This is necessary for the new simplified release process and is done
ahead of time once for the upcoming release now.
After osbuild 40 this will be done by the GitHub composite action.
This commit changes our release process from the model of having a
release commit (and pull request) which also updated the NEWS.md file
and bumped the versions in the osbuild.spec and setup.py files to simply
pushing a tag.
After the tag (containing the release notes) is pushed, a GitHub
composite action is triggered that creates a GitHub release with the
contents of the git release tag. Furthermore the bumping of the version
number now always has to happen directly after a release to avoid having
to push a(n untested) commit to main for the release and this is also
handled by the GitHub composite action.
Finally packit pushes directly to dist-git now on pushing the release
tag, so no pull-request needs to be reviewed and merged anymore.
