This PR does a few related things to dump_devinfo:
- Store the raw discovery result in the fixture.
- Consolidate redaction logic so it's not duplicated in dump_devinfo.
- Update existing fixtures to:
- Store raw discovery result under `result`
- Use `SCRUBBED_CHILD_DEVICE_ID` everywhere
- Have correct values as per the consolidated redactors.
Also updates CI pypy versions to be 3.9 and 3.10 which are the currently
[supported
versions](https://www.pypy.org/posts/2024/01/pypy-v7315-release.html).
Otherwise latest cryptography doesn't ship with pypy3.8 wheels and is
unable to build on windows.
Also updates the `codecov-action` to v4 which fixed some intermittent
uploading errors.
