Feature requrest [I can do it myself if allowed]: Allow configuration of `pytest-examples` from `pyproject.toml`

Summary

Hey everyone!

I use pytest-examples in my small library and I see that at least pydantic-ai uses it
So I would like to make this library better
My initial PR was to enable pytest-examples on Windows, and now I would like to make it configurable via pyproject.toml

Here are examples of how I currently do this in my own library:

Example of how I pass my configurations:
https://github.com/Danipulok/pydantic-jsonschema/blob/3d14999a72bc873f3879cbbf30fe43cd6c6035ca/tests/test_docs.py#L12-L42

Example of the pyproject.toml I use:
https://github.com/Danipulok/pydantic-jsonschema/blob/3d14999a72bc873f3879cbbf30fe43cd6c6035ca/pyproject.toml#L257-L263

If allowed, I will see what options should be enabled etc., and simply will pass then as I do in my own code, but inside the library.

PS

I'm ready to help and would like to make this library better, so I can update all the deps, QOL, typehints and etc.
For this I would need someone to guide me (a little bit, I'm pretty independent) and merge PRs
I'm sure that samuelcolvin is pretty busy, but maybe someone from pydantic team would be able to spend like 10 minutes a day for this?

Start by comparing the referenced pydantic-jsonschema tests/test_docs.py configuration with its pyproject.toml example. Identify which pytest-examples options should be configurable and verify that equivalent settings work through pyproject.toml, with tests covering the supported configuration.
