[madgraph2022 build v0.2] First version of "madgraph 2022" container (v0.2) truly using 2022 upstream code

First version of "madgraph 2022" container (v0.2) truly using 2022 upstream code.

This also contains several improvements in common code.

I will document all changes later on. Now I create amd merge the MR to launch the container build in the official qa.

@giordano I will ask you to review the later merge to master.
