system-maintenance: Download workstation OSTree repo from GitHub

The repo is now being built automatically by a GitHub action:
https://github.com/martinpitt/ostree-pitti-workstation/actions

Also move from a persistent to a temporary remote, to reduce the
assumptions on the already installed system.
