[Systemroles] Network Role: New base/default branch: main

Hi everyone, the network system role is now only using the branch "main" as default branch. The old default branch has been removed. I adjusted the open PRs to base on main now. If you have any repository clones, please adjust them accordingly. If you have any questions, please let me know.
