Move away from set-output (while updating all deps) (#148)

* Update all our deps

Get rid of warnings such as:
* `save-state` will be deprecated
* `set-output` will be deprecated
* nodejs 12 is being deprecated
...

Rely on tests to make sure the actions still works

* Fix as per CI results

* Get rid of deprecated containers

* Have a warningless run

We're not testing rebar3 here, in any case
