[STLink] Failed to flash Nucleo L496ZG(-P) under Linux and Mac

[fpistm]

Current version delivered of texane STLink is 1.3.0.
It does not support Nucleo L496ZG(-P).
Latest version 1.5.0 add this support:
https://github.com/texane/stlink/releases/tag/1.5.0

Anyway, it does not support H7.
One solution is to replace Texane STLink by STM32CubeProgrammer which is now multi-OS:

Multi-OS support: Windows® , Linux® , macOS®
