Fix missing apt-get install command in Ubuntu dependency step

[Copilot]

The Install Qt/OpenGL runtime deps step was missing sudo apt-get install -y \, causing the package names (libegl1, libgl1, etc.) to be executed as shell commands and fail.

Fix

Restored the sudo apt-get install -y \ line before the package list:

- name: Install Qt/OpenGL runtime deps (Ubuntu)
  run: |
    sudo apt-get update
    sudo apt-get install -y \
      libegl1 \
      libgl1 \
      libopengl0 \
      libxkbcommon-x11-0 \
      libxcb-cursor0
