Extensions for AEM and IMS do not follow the proper hierarchy in the repo

## What are the schemas that are affected by the issue
\extensions\IMS
\extensions\AEM

## What are examples of products that are impacted by the issue
Not sure.

These schemas should be under a \extensions\adobe\shared\IMS and \extensions\adobe\experience\AEM or simular hierarchy.

Start by reviewing the schemas in extensions/IMS and extensions/AEM and compare their locations with the proposed extensions/adobe/shared/IMS and extensions/adobe/experience/AEM hierarchy. Done means the affected schemas follow the agreed hierarchy without breaking their repository organization.
