Improve the EKS Blueprints Add-ons description

[Yevhenii Pokhvalii]

Please rename the point With the EKS Blueprints Framework to With the EKS Blueprints Framework for Terraform. Otherwise, it gives an impression that Argo CD is capable of deploying Kubernetes clusters.

Also, this
Please see the ArgoCD add-on documentation for details on how to easily bootstrap an EKS cluster

That 'bootstrap' thing. As if you are able to deploy a Kubernetes cluster with Argo CD from scratch.
Please mention that you need to create a cluster with Terraform in the first place

Thank you for the feedback - this project was originally designed to serve two different methodologies: EKS Blueprints for CDK and EKS Blueprints for Terraform. The Terraform flavor is currently undergoing some changes and you will see some updates coming soon for this - for now here is the repository that manages addons using the Terraform route https://github.com/aws-ia/terraform-aws-eks-blueprints-addons

Here is the issue that talks more about the changes happening on the Terraform side aws-ia/terraform-aws-eks-blueprints#1421

And for the GitOps based deployments, we have an open issue where we are collecting feedback as we re-think the integration between Terraform and GitOps operators aws-ia/terraform-aws-eks-blueprints-addons#114
