[Assets] Clarify how many Smart Crop settings are supported

[#1]

Request for Feature Enhancement (RFE) Summary:	We were advised to only create 5 smart crops since there will be performance implications if there are more. THere's no limit in the UI but what Adobe said, we should not exceed 5
Use-case:	Our organization needs a lot of smart crops since the assets in DAM are being used on different channels. Having a limit of 5 will make it difficult for us to support our customers;' needs
Current/Experienced Behavior:	Only 5 smart crops are requested to be created
Improved/Expected Behavior:	The system should have more capacity to accommodate more smart crops
Environment Details (AEM version/service pack, any other specifics if applicable):	ACS
Customer-name/Organization name:	N/A
