Make rugged compatible with Orekit 12

This is an attempt at making Rugged compatible with Orekit 12 (addresses #395 (closed) ).

There are two things where I am not super sure:

• Some unit tests required higher error thresholds than before... The deviations were small but still higher than the old thresholds. I don't know Orekit enough to know what in Orekit 12 caused this deviations
• I tried to update the Gitlab CI configuration because I got this error because SonarQube was updated: https://gitlab.orekit.org/orekit/rugged/-/jobs/17122
  • I modified the pom.xml and .gitlab-ci.yml files to be more similar to the same files in the latest develop branch of the orekit repo. However, I didn't manage to make it work, I got an issue with the sonar login: https://gitlab.orekit.org/orekit/rugged/-/jobs/17128
