Added undescore to ignore new pydocstyle item

Pydocstyle 6.2.0 introduced a new feature where get_files_to_check method yields 4 items instead of 3.

This PR adds and ignores that item, so the tests can run without crashing.

Could we get a release in foxy so we can get this change please? I believe everyone's foxy CIs for ros2 python packages are failing without this change right now. Thanks!
