feat: adaptive username (#536)

> When executing npm cli owner add command,
[ref](https://github.com/npm/cli/blob/latest/lib/commands/owner.js#L151),
it causes errors due to duplicate additions，when the selfRegistry
configuration has the userPrefix option enabled.
1. 🧶 Modify the user query api to prioritize returning users from
selfRegistry
2. 🧶 Ensure that the query api uniformly returns displayName

---------

> npm cli 执行 owner add 时
[ref](https://github.com/npm/cli/blob/latest/lib/commands/owner.js#L151)，依赖查询结果做去重，selfRegistry
配置 userPrefix 时会导致重复添加报错
1. 🧶 修改用户查询接口，优先返回 selfRegistry 内的用户
2. 🧶 查询接口统一返回 displayName
