Bug: SonarQube project name issue

It looks like SonarQube always uses project "oreczml-parent" indistinctively for forks or the origin repository.
This is annoying because it becomes hard to distinguish who's who and where the errors may come from( original repo or personal fork ?).
We should set up variables in gitlab-ci.yaml like in Orekit (see here) to fix this issue.

Potential Side-effect: All contributors will probably have to relaunch a pipeline on master branch (or main if the swith has been done) to initiate their personal project on Sonar
