Continuous Integration artifacts are now built only once a day (nightly builds) and include Gtk+ versions

* The CI tests are unchanged. The workflow file has been renamed to ci.yml, though.
* Nightly builds are described by nightly.yml and are built at 4:13.
* Nightly Ubuntu package builds now include the Gtk+ 3 packages.
