Initial Checks

• I confirm that I'm using the latest version of Pydantic AI
• I confirm that I searched for my issue in https://github.com/pydantic/pydantic-ai/issues before opening this issue

Description

https://ai.pydantic.dev/retries/#custom-retry-logic
I directly copied the code and type checker complains. Seems the RetryConfig argument should be retry=retry_if_exception(custom_retry_condition).

Example Code

Python, Pydantic AI & LLM client version
