Patch format-exception-only too

[Zac-HD]

Fixes #7, ensuring that e.g. Pytest's traceback formatting (which uses format_exception_only()) will also show notes.

Did the test suite pass for you locally?

[agronholm]

You should pull in the pre-commit changes (or install the pre-commit hook locally) instead of force pushing the changes.

[Zac-HD]

Sorry for the churn - turns out that when running pytest directly I needed to do a full non-editable install before testing each change. Pre-commit is also now installed and working on my new laptop 👍

[agronholm]

Shouldn't the 3.11 tests pass already btw? It runs on 3.11a7 now.

[agronholm]

Hm, it does pass for me locally and I'm using the git version beyond a7 so I guess it's all okay.

[agronholm]

Just a couple code style changes, otherwise looks fine. I'll go ahead and commit those style changes.

[agronholm]

Thanks!

Released v1.0.0rc5.

[Zac-HD]

Thanks @agronholm! While I'm hoping this is the last time I need to come back here, that's not because I don't appreciate working with you 😀

The .add_note() patch was merged into CPython shortly after a7, so they're on main/mightlies and will be released in beta1.
