`--snapshot-default-extension` doesn't support pytest 7 `pythonpath`
**Describe the bug**

`--snapshot-default-extension` doesn't support pytest 7's `pythonpath` configuration option, for pytest-only additions to the Python path.

For my project, I'm using `--snapshot-default-extension` so the right extension and serializer are in place, before Syrupy begins its reporting. My Syrupy extensions are for tests only, so they live outside of my src/ folder. Only the src/ folder of my project seems to be on the default Python path. So when running tests, I need to tell Syrupy about my extensions, somehow. I'd love to use the vanilla `pytest` command directly, configured in pyproject.toml, without having to pass a custom `PYTHONPATH` to `pytest` every time.

**To reproduce**

See my branch, [john-kurkowski/syrupy#default-extension-pythonpath](https://github.com/john-kurkowski/syrupy/compare/main..default-extension-pythonpath). In the final commit,  https://github.com/john-kurkowski/syrupy/commit/ea9779371583253c03b0bdf47c09ca6f5526d909, switching from modifying `sys.path` to setting pytest's `--pythonpath` breaks 2/3 of the branch's test cases. **EDIT:** pytest's `pythonpath` an INI configuration option, not CLI.

**Expected behavior**

Tests in my branch should pass.

**Environment:**

- OS: macOS
- Syrupy Version: 4.0.1
- Python Version: 3.11.1

**Workaround**

Set `PYTHONPATH` prior to invoking the pytest CLI. 

```sh
PYTHONPATH=path/to/my/extensions/folder pytest --snapshot-default-extension some_module.SomeExtension
```
