Mistral models do not work in Temporal workers using PydanticAIPlugin

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

When using Mistral models, which internally imports httpcore module, we have errors inside the Ttemporal worker, PydanticAIPlugin does not allow httpcore package to pass through and we have a strange exception.

I am trying to run this example repo

Resolution

Adding Either httpcore or anyio to the runner.restrictions.with_passthrough_modules method call arguments in PydanticAIPlugin class solves the problem. I am not sure what is the best fix for this .

Example Code

mistralai                                1.9.10

@slumbi That's a reasonable fix, can you submit a PR that adds those 2?
