[Webform] Remove Git commit

The Webform 8.x-4.x branch is obsolete, but it should remain for historical reasons. The last commit on that branch erases everything. There is no need for this, so I would like to undo that last commit. I would like to run the following, but drupal.org does not accept the forced push. Is there someone who can run this?

git checkout 8.x-4.x && git reset --hard HEAD~1 && git push -f
