Add uv script at top of example

[raybellwaves]

Any thoughts on adding requirements to the top of the example scripts like I have done here?

It can make the examples even easier to run as a one-liner and it doesn't affect any existing functionality.

You can try it using uv run https://raw.githubusercontent.com/raybellwaves/pydantic-ai/refs/heads/add-uv-script-at-top-of-example/examples/pydantic_ai_examples/pydantic_model.py

This seems unnecessary. We already distribute examples as a separate package that includes required dependencies. I also thing this would be a significant maintenance burden as we have to keep dependencies that are crammed into python files up to date and in sync.

What's the advantage?
