[Pharo-project] ssl fails on build CI

The FileSystem-Git builds on CI generate many test failures because the SSL plugin is missing (apparently) here's the output: https://ci.inria.fr/pharo-contribution/job/FileSystem-Git/6/PHARO=20,VERSION.... Is that to be expected? I gathered from a recent thread that at least libssl should be present on the CI servers. Or do I need to change something in the configuration? Max
