Schema Inaccuracy

When retrieving a repository that is unavailable for legal reasons (e.g. a DMCA takedown request), the GitHub API responds with an HTTP status "451 Unavailable For Legal Reasons" and a response body such as:

{
    "message": "Repository access blocked",
    "block": {
        "reason": "dmca",
        "created_at": "2021-04-22T17:53:56Z",
        "html_url": "https://github.com/github/dmca/blob/master/2021/04/2021-04-20-ultimate-character-controller.md"
    }
}

This response code and error body are not described in the schema.

Relevant schema excerpt:

  "/repos/{owner}/{repo}":
    get:
      summary: Get a repository
      description: |-
        The `parent` and `source` objects are present when the repository is a fork. `parent` is the repository this repository was forked from, `source` is the ultimate source for the network.

        **Note:** In order to see the `security_and_analysis` block for a repository you must have admin permissions for the repository or be an owner or security manager for the organization that owns the repository.
