(this issue was reposted from https://github.com/orgs/community/discussions/150535, cc https://github.com/yanyongyu/githubkit/issues/188)

Current definition:

      "state_reason": {
        "description": "The reason for the current state",
        "type": [
          "string",
          "null"
        ],
        "enum": [
          "completed",
          "reopened",
          "not_planned",
          null
        ],
        "examples": [
          "not_planned"
        ]
      },

Expected
