+ * The type of the `RulesConfig` have changed in [commitlint v20.3.1](
+ * https://github.com/conventional-changelog/commitlint/releases/tag/v20.3.1),
+ * and are no longer compatible with those from v19. Specifically the types of
+ * the `scope-case` and `scope-enum` rules have been changed to also accept a
+ * rule object. While the individual versions are able process this test without
+ * runtime or type errors, the combined signature causes type errors. To keep
+ * the test, a relatively long one, the same for both versions, the type of the
+ * rule config is cast.
