PR Description: Blueprint Removal and Updates
We have identified several blueprints that are either not used by customers or have no demand from users and Solution Architects. Therefore, we are deprecating and removing these blueprints. Below is the list of the blueprints that have been removed and their respective links:

Descoped and Removed:

1. Ray blueprint has been removed. The replacement for this is the JARK stack. Documentation has been updated accordingly.
2. CDK Folder removed. This folder consisted of the emr-eks and stream-emr-eks blueprints.
3. emr-eks-ack
4. emr-eks-fargate

Retained and Maintained:

• emr-eks-karpenter is the only blueprint that will continue to be referred to and maintained for customers.

Updated:

• The Ray documentation has been updated to point to the JARK stack blueprint.

Further Considerations:

• Remove MLFlow blueprint and integrate ML Flow with JARK stack
• Remove NiFi Blueprint

### If anyone is who is looking for the deleted blueprints then they can refer to this Release v1.0.3 tag
