Temporary Export Files Not Deleted Automatically, Leading to Storage Issues

**Describe the bug**
I have been using Label Studio for almost a year for image annotation (object detection, segmentation, etc.). Recently, my remote server has been running out of storage space. Upon investigation, I found that temporary files were not being deleted automatically. This issue seems related to Docker itself.

After running the Label Studio container, I noticed that the directory `/var/lib/docker/overlay2/2cba2b496509f78e63274c6b9bcff18eb43c0fbe55c06ecfc684a1f883902aa3/merged/tmp` (associated with the Label Studio container layer) contained thousands of zipped files introduced after each export, which were supposed to be deleted automatically.

**To Reproduce**
1. Run Label Studio using the following command:
```sh
docker run -d -it -e LABEL_STUDIO_DISABLE_SIGNUP_WITHOUT_LINK=true -p 8080:8080 -v $(pwd)/mydata:/label-studio/data heartexlabs/label-studio:latest
```
2. Export any project.
3. Observe that the exported images are saved in the mentioned location as zipped files, which are not deleted automatically.

**Expected behavior**
Temporary files created during the export process should be deleted automatically to prevent storage issues.

**Environment (please complete the following information):**
- OS: Ubuntu 22.04
- Label Studio Version: latest
