TemporaryDirectory ignore_cleanup_errors flag is not robustic

Bug report

Bug description:

When using ignore_cleanup_errors flag in TemporaryDirectory context manager, there's a path that will raise an issue.

In the onerror function that's being called when error in rmtree function:
If the first error is FileNotFound, pass
If it's everything else, check the ignore_errors flag, and raise if set to False
if the error was PermissionsError first try to change the permissions (the call to _resetperms , and then try to remove the files again. But the the call to resetparams is in an outer try, which is a lot weaker, and catching only the FileNotFoundError . But in our case, this very call raised PermissionError (yet again). It was not caught and raised back to our code.

tempfile.py の _resetperms と TemporaryDirectory のクリーンアップパスから始め、shutil.rmtree の onerror 処理と比較してください。macOS または Linux 上の Python 3.11 で PermissionError のケースを再現し、ignore_cleanup_errors によってクリーンアップの失敗が外部に伝播しないことを示す回帰テストを追加してください。
