Describe the bug:
The setup command creates

• HLD repo
• Manifest repo
• HLD --> Manifest pipeline

The HLD --> Manifest pipeline relies on the existence of a variable group. The current code doesn't seem to create that for you. We need to create a variable group before we create and queue the pipeline.

The first instance of variable group creation happens here during App repo set up (which comes after HLD --> Manifest pipeline creation.

Work around:
The work around for this is to have a pre-existing variable group named quick-start-vg in your AzDO project

Expected behavior:
We should create the variable group prior to the HLD --> Manifest pipeline

Does this require updates to documentation?:
NO
