This commit resolves an issue where using Mistral models within a Temporal worker would fail due to `httpcore` not being available in the sandboxed environment. The `PydanticAIPlugin` has been updated to include `httpcore` in the list of passthrough modules, ensuring its availability to the worker. Fixes pydantic#3117

This pull request addresses the issue where Mistral models fail when used within a Temporal worker due to the
httpcoremodule not being accessible.Changes include:
Updating PydanticAIPlugin in pydantic_ai_slim/pydantic_ai/durable_exec/temporal/init.py to include httpcore in the with_passthrough_modules list.
This ensures that models with a dependency on httpcore can now be used seamlessly within Temporal workers.
Fixes #3117
