ref: upgrade structlog (#43680)

I think this fixes a breakage with xdist:

```console
  File "/home/runner/work/getsentry/getsentry/.venv/lib/python3.8/site-packages/sentry_sdk/integrations/logging.py", line 96, in sentry_patched_callhandlers
    return old_callhandlers(self, record)
  File "/opt/hostedtoolcache/Python/3.8.13/x64/lib/python3.8/logging/__init__.py", line 1661, in callHandlers
    hdlr.handle(record)
  File "/opt/hostedtoolcache/Python/3.8.13/x64/lib/python3.8/logging/__init__.py", line 954, in handle
    self.emit(record)
  File "/home/runner/work/getsentry/sentry/src/sentry/logging/handlers.py", line 92, in emit
    logger.log(**self.get_log_kwargs(record=record, logger=logger))
  File "/home/runner/work/getsentry/getsentry/.venv/lib/python3.8/site-packages/structlog/_config.py", line 396, in __getattr__
    return getattr(bl, name)
AttributeError: 'BoundLoggerFilteringAtNotset' object has no attribute 'log'
```
