Update nvidia-390-glx-driver to 390.143 and rework descriptions
- Fixed a bug where vkCreateSwapchain could cause the X Server to crash when an invalid imageFormat was provided
- Fixed a driver installation failure on Linux kernel 5.11 release candidates
Packaging change: Restructure the descriptions the same way as for the nvidia-glx-driver packages. Make it clear which one is the LTS driver in the description too.
