`includes` configuration is documented but not valid

[Neil Drumm]

Describe the bug
https://github.com/composer/satis/blob/main/docs/config.md#includes says includes can be configured.

https://github.com/composer/satis/blob/main/res/satis-schema.json does not have it.

To Reproduce

{
    "name": "drupal/test",
    "homepage": "http://test.example.org",
    "repositories": [
        { "type": "vcs", "url": "https://github.com/drupal/core-composer-scaffold.git" },
        { "type": "vcs", "url": "https://github.com/drupal/core-project-message.git" },
        { "type": "vcs", "url": "https://github.com/drupal/core.git" },
        { "type": "vcs", "url": "https://github.com/drupal/core-recommended.git" }
    ],
    "require-all": true,
    "includes": true,
    "archive": {
        "directory": "dist",
        "prefix-url": "http://test.example.org"
    }
}

satis build --minify satis.json output

Outcome

Attempting to use it errors with

The property includes is not defined and the definition does not allow additional properties

In BuildCommand.php line 348:

  The json config file does not match the expected JSON schema

Expected behavior

I do not want to support Composer 1.

Looks like 73922c7 was incomplete. Odd that this was not reported earlier though. I guess because it defaults to true in the code, the only use case is when you explicitly do not want it (setting it to false) or when you want your configuration to be explicit rather than default.
