After change the privilege model of Beyla, we wrote a documentation regarding the required capabilities depending the operational mode. In out docs, we still have some places (like setup or tutorials) which reflects the old privilege model.

Hi @grafsean! I'm Yana and I'm interested in getting started on this project. I see that you were assigned so I was wondering if you already got started or if it's ok for me to try to address this one?
