`atmos describe affected` does not show the project name if the atlantis integration is enabled

Describe the Feature

Add integrations to the output of the atmos describe affected

Expected Behavior

When I run :

atmos describe affected --ref refs/heads/main --verbose=true

the output is:

   {
      "stack": "pepe-ue2-lab",
      "component_type": "terraform",
      "component": "vpc",
      "affected": "stack.vars"
   }
]

if atlantis integration is enabled it will be useful to have the project name added to the output like 👍🏽

   {
      "stack": "pepe-ue2-lab",
      "component_type": "terraform",
      "component": "vpc",
      "affected": "stack.vars"
      "atlantis_project_name": "pepe-ue2-lab-vpc"
   }
]

Use Case

since Atlantis supports dynamically generated atlantis.yaml files it is possible to generate an atlantis.yaml for only the affected component/s and this way limit the blast radius of a PR significantly.

Alternatives Considered

parsing yaml until is not fun anymore....

it might be even better to add an atmos atlantis generate repo-config --affected option to be able to create the atlantis.yaml. RB (@nitrocode)
