fix: rename includeCommerce to includeCif

[Buuhuu]

Description

When creating a new project in cloud manager using archetype, cloud manager passes all solutions enabled to the archetype maven plugin, like -DincludeSites=y, -DincludeAssets=y, ... and also -DincludeCif=y. However, we called it includeCommerce and not includeCif. With this PR we rename the property in order to match what cloud manager is using.
