Book cannot be built anymore

[mpcjanssen]

The Pillar Pharo 4.0 CI build being used for building this book is not available anymore:. The dead URL is:
https://ci.inria.fr/pharo-contribution/job/Pillar/PHARO=40,VERSION=stable,VM=vm/lastSuccessfulBuild/artifact/Pillar.zip

It also seems that newer pillar versions don't support the inputFiles configuration in pillar.conf anymore so just using an newer version doesn't work.
