cake 5: Support parameters with only type hints

Starting with cake 5, some function parameters won't have matching docblock @param annotations.

Do we want to still list these parameters in the parameter block with no description or should we hide them?

These parameters won't have a matching annotation because PHP 8 allows union types that fully documents the allowed types and the parameter name is self-documenting (the annotation description isn't helpful).

首先检查带有 PHP 8 类型提示的 CakePHP 5 参数在 API 文档中的表示方式。确定没有匹配的 @param 注解的参数应显示为空描述，还是应被隐藏，然后为所选行为添加覆盖测试。
