Resolved package dependency in classic all project

[davidjgonzalez]

Fixed issue where aem-guides-wknd-shared.ui.content v3.0.0 was being set as a package dependency even in the -classic artifact.

This fix sets aem-guides-wknd-shared.ui.content v3.0.0 as a dep in the cloud artifact, and v2.2.2 as a dep in the classic artifact.

Note that the aem-guides-wknd.all-3.0.0-classic.zip in https://github.com/adobe/aem-guides-wknd/releases/tag/aem-guides-wknd-3.0.0 contains this fix retroactively.
