Revert "Revert "Revert "Turn on anaconda-webui for workstation"""
This reverts commit 3fe657c2fe67f2da37c302d08b3414566d54ff1c.
It's the rare triple reversion! FESCo has decided to invoke the
contingency plan for
https://fedoraproject.org/wiki/Changes/AnacondaWebUIforFedoraWorkstation
and push the webUI out to Fedora 40, so we need to turn it off
again for Fedora 39.
