pytest-xdist is not being ignored in code samples

The `xdist` module has been in the code capture ignorelist since #8290.
However, this is from the most recent coiled/benchmarks run:

```python
Span test_query_1 in /home/runner/miniconda3/envs/test/lib/python3.12/site-packages/xdist/remote.py
def run_one_test(self):
self.item_index = self.nextitem_index
self.nextitem_index = self._get_next_item_index()

items = self.session.items
item = items[self.item_index]
if self.nextitem_index is self.SHUTDOWN_MARK:
nextitem = None
else:
nextitem = items[self.nextitem_index]

worker_title("[pytest-xdist running] %s" % item.nodeid)

start = time.time()
self.config.hook.pytest_runtest_protocol(item=item, nextitem=nextitem)
duration = time.time() - start

worker_title("[pytest-xdist idle]")

self.sendevent(
"runtest_protocol_complete", item_index=self.item_index, duration=duration
)
Span test_query_1 in /home/runner/work/benchmarks/benchmarks/tests/tpch/test_dask.py
@pytest.mark.shuffle_p2p
def test_query_1(client, dataset_path, fs, scale):
dask_queries.query_1(dataset_path, fs, scale).compute()
```
