    flatpak: update SDK runtimes along with dependencies
    
    These are also dependencies of the project, and we should update them as
    necessary so that our private SDK installation directory does not fall out
    of date.
    
    We will still need to elevate out-of-date dependencies in the project
    tree at some point once we can query the peers manually.
