## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

Similiar to astral-sh/ruff#17941.

`Replacement::Name` was designed for linting only. Now, we also want to
fix the user code. It would be easier to replace it with a better
AutoImport struct whenever possible.

On the other hand, `AIR301` and `AIR311` contain attribute changes that
can still use a struct like `Replacement::Name`. To reduce the
confusion, I also updated it as `Replacement::AttrName`

Some of the original `Replacement::Name` has been replaced as
`Replacement::Message` as they're not directly mapping and the message
has now been moved to `help`


## Test Plan
