The root build is a modular super-project: libretroshare, retroshare-gui, retroshare-service, retroshare-friendserver and plugins are each a standalone CMake project that the top-level CMakeLists.txt only aggregates (and they live in separate git repos pulled as submodules). Rename project(retroshare-monorepo) -> project(retroshare-superproject) and reword the CI header comments. Purely cosmetic: the old name was referenced nowhere.
