Add more information when an InvalidTag occurs and a link to the phpDocumentor documentation

In issue https://github.com/phpDocumentor/phpDocumentor/issues/3378, there was some confusion because the Author tag does not support a description. When the StandardTagFactory encounters a situation where an InvalidTag is generated, it would be nice if it could ask the Tag class what the expected format is and a link to the documentation; and include that in the InvalidTag so that phpDocumentor can provide better error messages in the error report

首先阅读 StandardTagFactory、InvalidTag 以及 issue 中描述的 Tag 类行为，然后查看 issue 3378 中的相关讨论。完成标准是 InvalidTag 实例包含预期的 tag 格式以及指向相关 phpDocumentor 文档的链接，从而让错误报告提供更清晰的指导。
