Bug description:
  [Impact]

   * In Ubuntu 22.04, ubuntu-drivers install will install nvidia-470 instead of 
510. (the ubuntu-drivers install is the best and recommended way to install 
nvidia driver).
   * nvidia-470 is LTSB (although webpage shows PB) and nvidia-510 is PB, in 
this case, we need to chose the newer version since the support is fair in both 
version.
   * Also, 22.04 announces Wayland supports but nvidia-470 doesn't support in 
Wayland scope at least from gdm upstream.

  [Test Plan]

   * Call "ubuntu-drivers debug" and check that 510 is marked as 
"(auto-install)"
  ```
  ...
  === matching driver packages ===
  nvidia-driver-510: installed: <none>   available: 510.54-0ubuntu2  [distro]  
non-free  modalias: pci:v000010DEd000025A0sv00001028sd00000A61bc03sc02i00  
path: /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0  vendor: NVIDIA 
Corporation  model: GA107M [GeForce RTX 3050 Ti Mobile]
  ...
  nvidia-driver-470: installed: <none>   available: 470.103.01-0ubuntu2 
(auto-install)  [distro]  non-free  modalias: 
pci:v000010DEd000025A0sv00001028sd00000A61bc03sc02i00  path: 
/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0  vendor: NVIDIA Corporation  
model: GA107M [GeForce RTX 3050 Ti Mobile]  support level: LTSB
  ...
  ```
   * As you can see, "(auto-install)" points to 470 because it owns LTSB tag.

  [Fix]
   * Adjust the priority in UbuntuDrivers/detect.py, if the PB and LTSB 
versions found, then it needs to pick the newer version one.

  [Where problems could occur]
   * It has less possible to introduce regression since the patch only changes 
_cmp_gfx_alternatives() which counts the priority of nvidia drivers be 
installed.
   * In Ubuntu, we have nvidia-390, 470 and 510 so far as I known and these 
cases are listed in test_system_driver_packages_chroot_support_branch_pb.

  + nvidia-graphics-drivers-510 (510.54-0ubuntu0.20.04.1)
  +
  +   * New upstream release (LP: #1961075):
  +     - Fixed a bug that could cause GPU exceptions when minimizing a
  +       fullscreen Vulkan application on certain desktops, such as
  +       Plasma.
  +   * debian/templates/control.in:
  +     - Set XB-Support to PB (production branch).
  +   * debian/rules.defs:
  +     - Add support for video ABI 25.

  ---

  Since
    * debian/templates/control.in:
      - Set XB-Support to PB (production branch).

  The u-d-c will choose LTS branch instead of PB branch.

  because `def _cmp_gfx_alternatives(x, y):` doesn't define PB.

  If installed 470 instead of 510, then it will cause
