Linux Qt binding granurality

Changelog Description

Added distro python module to detect linux distribution name used for detection of Qt binding. Also added option to use PySide2 during docker build.

Source issue

Rocky 8 might not support PySide6 by default and that might require to use PySide2 instead of PySide6. That was case because of specific rocky 8 state and GPU drivers. For now that is considered as edge case as most of machines should use PySide6 by rather.

Error

qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.

[iLLiCiTiT]

We do the same for centos7 by adding ENV QT_BINDING=centos7 in docker, so now we have 2 different approaches to that, so we should probably remove the env from docker image.

Modified the original PR to be able to build any linux installer with PySide2.
