If you're doing this outside of the bindings/python directory, try specifying the config file:

```
(xtf-py3.12) vfazio@vfazio4 ~/development/libgpiod $ mypy --config-file=bindings/python/pyproject.toml --strict bindings/python/gpiod
Success: no issues found in 13 source files
```

However, if you run it on `bindings/python` the output will be noisy because it's not limiting itself to the "files" section within the mypy settings.

I wrote the pyproject settings with the unwritten rule that the checks would be rooted within `bindings/python` and not outside of it.

We should probably document our expectations for how these checks are run and then update the config file to respect those expectations.
