Powershell: Powershell generating files in /tmp but does not delete them

[BlacksWise]

The same error as mentioned in #11599 still persists, which leads to an immense amount of files within the /tmp directory.

pwsh --version
PowerShell 7.0.3

OS:
5.4.0-42-generic #46~18.04.1-Ubuntu

Steps to reproduce

Just execute any script on linux system

Expected behavior

Temp files get deleted after script execution

Actual behavior

Temp files do not get deleted and can cause the system to be unbootable until /tmp gets purged in Single User Mode
