Bug description:
  [ Impact ]

  In Ubuntu 24.04 the NVIDIA drivers 570 or newer break the
  EGL_PLATFORM_WAYLAND_EXT extension, preventing most graphical
  applications from using OpenGL in a Wayland session.

  The libnvidia-egl-wayland.so.1 library implementing the
  EGL_PLATFORM_WAYLAND_EXT extension has an incorrect version check
  which makes it refuse to load on the newer NVIDIA drivers.

  This was fixed upstream by: https://github.com/NVIDIA/egl-
  wayland/pull/106

  [ Test Plan ]

  1. Set up Ubuntu 24.04 on a machine with an NVIDIA GPU
  1. Install an affected NVIDIA driver:
     $ sudo apt install nvidia-driver-570
  2. Install the update with:
     $ sudo apt install -t noble-proposed libnvidia-egl-wayland1
  2. Log in to "Ubuntu on Wayland"
  3. Run in a terminal:
     $ eglinfo -B -p wayland
     Verify that it prints information about your NVIDIA card and driver
  4. Open Settings > System > Info > Details
  5. Verify that it detects your NVIDIA GPU.

  [ Regression Test Plan ]

  Perform the same steps as the main Test Plan, but using an older NVIDIA driver:
  $ sudo apt install nvidia-driver-560

  [ Where problems could occur ]

  The change inverts a version check, so there is a risk that the older
  NVIDIA drivers the used to be working will stop working. The [
  Regression Test Plan ] verifies that this is not the case.
