Deterministic alias selection for init kwargs doesn't support `validate_by_name`

[Mantisus]

Recent fix #688 works perfectly with populate_by_name, but doesn't support validate_by_name.

Current Pydantic documentation recommends using ConfigDict(validate_by_name=True, validate_by_alias=True) instead of ConfigDict(populate_by_name=True)

I am not certain what is expected here but I created a MR with how I understand the problem. Let me know if that's what you want.
