Install system dependencies using remotes from GitHub

* We need the development version of remotes to support Ubuntu 22.04 and for querying system requirements for multiple pkgs (r-lib/remotes<>665), which we apply to all packages locked in `renv.lock`.
* Note that we deactivate renv to have an renv-free `remotes::system_requirements()`, in particular to get a clean stdout. `r-lib/actions/setup-renv` will reactivate renv.
