Task Description (Required)

_<Task description> _

After the conclusion of https://issues.redhat.com/browse/DEVHAS-735 we verified the steps required to manually setup GitOps and ArgoCD alongside Vanilla RHDH. The scope of this issue is setting up the Helm Chart / scripts necessary to create the GitOps Operator, ArgoCD instance, and Pipelines Operator with default values. Default values in this case mean they are simply installed and not configured as configuration will occur in a separate issue. RHTAP currently has a Helm Chart they use for setup that we can reference. 

The following will need to be accomplished as part of this issue:

1. Create a new repo in the AI org on GitHub that will be the home of this chart
2. Create Helm Chart for default installation of GitOps Operator, Pipeline Operator and ArgoCD
   1. Create GitOps Operator subscription
   2. Create Pipeline Operator subscription
   3. Create ArgoCD instance
