Please fill out all the sections below for bug issues, otherwise it'll be closed as it won't be actionable for us to address.

Describe the bug
Docker build timeout issue sometimes happened in SqlTools Untrusted workload initialization. The timeout is 5 mins. In .dockerfile, it needs to run PowerShell script to install .NET 8 SDK first and then run CMD command. It always completed .NET8 SDK installation but hang in CMD step (I will share the required files in "To Reproduce").

"Done unzipping contents of C:\SqlToolsCore.Untrusted\dotnet-sdk.zip to C:\Program Files\dotnet-sdk" is the log meaning that it completed SDK installation. But it never went to CMD

To Reproduce
Steps to reproduce the behavior:
There are the scripts in untrusted workload:
docker file
install SDK script

This is the install docker script:
InstallDocker.ps1
workloadbase-windowsservercore-untrusted.dockerfile

Expected behavior
Docker build should complete within 5 minutes.

Configuration:

• Edition: WindowsServerCore
• Base Image being used: mcr.microsoft.com/windows/server:ltsc2022
• Container engine: [docker]
• Container Engine version [22]
