建议为 nz-icon 提供类似 signal-queries-migration 更友好的迁移命令

[cipchk]

很多情况下并不是通过 ng update 来升级的，特别是一些带有工作空间的情况下；个人觉得可以考虑增加类似：

ng generate ng-zorro-antd:nz-icon-element

作为已经是 Angular 19+ 项目的情况下，这样的命令还是非常有意义的。

[zorro-bot]

Translation of this issue:

Suggestion provides a more friendly migration command for nz-ICon

In many cases, it is not upgraded by ng update, especially when there are some work space; I personally think that it can be considered to add similar:

` ng generate ng-zorro -Ntd: icon-migration `

In the case of the Angular 19+ project, such a command is still very meaningful.
