The opensuse/leap image rolled forward to Leap 16, which ships Python 3.13 and no longer provides the python311-pip/python311-curses packages, so the pre-install step failed outright. Switch to the version-agnostic python3-pip/python3-curses names (which Leap provides via its python313 packages) so this does not break again on the next Python bump, and drop the manual python3 symlink that the packages already provide.
