Overview of the Issue

Currently, I im trying to add UnDiverged in my plan_requirements and apply_requirements via server-side configuration passed using the ATLANTIS_REPO_CONFIG_JSON environment variable:

{
  "version": 3,
  "delete_source_branch_on_merge": "true",
  "parallel_plan": "true",
  "parallel_apply": "true",
  "repos": [
    {
      "id": "/.*/",
      "plan_requirements": [
        "undiverged"
      ],
      "apply_requirements": [
        "mergeable",
        "approved",
        "undiverged"
      ],
      "allowed_overrides": [
        "apply_requirements",
        "plan_requirements",
        "delete_source_branch_on_merge",
        "repo_locking"
      ]
    }
  ]
}

Also running Atlantis with ATLANTIS_CHECKOUT_STRATEGY set to "merge"

I have found that there is an emoji that is not working as expected in Azure Devops in the message shown when creating a Pull Request to merge an outdated branch

Also, Atlantis is allowing me to run atlantis plan and atlantis apply even if the source branch is outdated. I am not sure if this is the expected behavior but as far as I understand from the Command Requirements documentation, this should prevent users to run plan/applies.
