datadogoperator app naming issue

[atifhafeez]

The name of datadog operator app in "https://github.com/aws-ia/terraform-aws-eks-blueprints" is "datadog-operator" which is different than the name in this repo here "datadogOperator".

If you are using terraform infra repo, it only allows its own name "datadog-operator" which does not exist here. Therefore, argocd does deploy this app if you set "argocd_manage_add_ons = true" there.

I believe, we need to adjust the name in this repo.
