Prevent content below nodes containing OSGi configuration #43
Description
During the Cloud image build CP2FM extracts all OSGi configuration from packages (https://github.com/apache/sling-org-apache-sling-feature-cpconverter?tab=readme-ov-file#osgi-configurations). Afterwards the according filter is being removed from the package. As the filter may also cover subnodes it is important that there is no other content there. The underlying issue in the cp2fm tool is tracked in https://issues.apache.org/jira/browse/SLING-12878.
