Remove the dependency to magnolia-module-data from ce-bundle. The Data module is only needed when migrating from 4.5 to 5.x. As a legacy leftover it causes some confusion to new 5.x users.

Functionally the Data module has been replaced with content apps. Technically there may be some dependencies which should be removed.

Background:

• 5.0 release notes: Announcing content apps as a replacement
• Migration instructions: Asking users to replace custom data types with content apps
