fix: 501 code

[elrrrrrrr]

Adjust the error codes related to the 'unpublish' feature:

• ⚠️ Unpublishing all versions is currently not implemented on the server side, return the 501 code.

• 🚨 When the search functionality is disabled, return 501 instead of 451.

调整 unpublish 相关错误码

• ⚠️ unpublish 所有版本目前服务端未实现，返回 501
• 🚨 未开启搜索功能时，也返回 501，替换原 451 错误码

为啥要返回 501？500+ 的 status 都是服务端异常，不合理啊。

在之前 audit 相关场景也是都是返回的 501。感觉配置没有开启的时候比较合适。

451 一般在法律政策相关的「非法」请求返回，感觉这个场景下似乎不太适合？cc @Beace

😂 npm 不同意 哈哈，超过 500 的 code 会触发 retry 逻辑，一直卡住
