fix: Disable warnings for model_* properties (#17066)

For model classes with model_something fields, pydantic raises a warning by default:
`Field "model_something" has conflict with protected namespace "model_".`.

These warnings make no sense here, because most users of the generator have established APIs
that they cannot change to conform to pydantic's safety rules.

Pydantic will raise an error if we ever conflict with a current attribute like `model_dump`.
