ResourceWarning: Implicitly cleaning up TemporaryDirectory

[nowtryz]

Describe the bug A ResourceWarningwarning is raised by python as a temporary file seems not to be cleaned properly when importing Monai.

To Reproduce

1. conda create -n monai-env python=3.11 -y
   conda activate monai-env
   

2. pip install monai[nibabel,einops]~=1.3.1
   

3. python -W error -c "import sys; sys.tracebacklimit=100; import monai"
   

Expected behavior Monai should import itself without triggering warnings

With name having the value 'monai._extensions'

Could be a duplicate of #6167, but the warning seems to be caused by monai and not pytorch if I am not mistaken.
