Install Qt/OpenGL runtime deps in CI

Add an Ubuntu-specific step to the python-package workflow to install Qt/OpenGL runtime dependencies (libegl1, libgl1, libopengl0, libxkbcommon-x11-0, libxcb-cursor0). This ensures CI runners have the required libraries for Qt/OpenGL-based install checks; the step runs apt-get update and installs the packages before the existing "Install tools" step.
