What Operating System are you using (both controller, and any agents involved in the problem)?

Reproduction steps

Before the recent refactoring there was

docker-agent/windows/windowsservercore-ltsc2019/Dockerfile

Line 26 in bd84740

FROM eclipse-temurin:"${JAVA_VERSION}"-jdk-windowsservercore-1809

(It's still the case, the refactoring hasn't changed any thing in the artifacts generated)

Expected Results

docker-agent windowsservercore-ltsc2019 images use a windowsservercore-ltsc2019 as base image.

Actual Results

docker-agent windowsservercore-ltsc2019 images use a windowsservercore-1809 as base image.

It appears that like Eclipse, Microsoft didn't publish any powershell:windowsservercore-ltsc2019 image 🤦

As I'm working on #349 in #459 it appears to me there are no powershell:nanoserver-ltsc2019 or powershell:windowsservercore-ltsc2019, only 1809 ones.

Thus we don't currently have a "proper" docker-agent windowsservercore-ltsc2019, it's based on a windowsservercore-1809 image.

@timja @slide @jenkinsci/team-docker-packaging WDYT about switching the base images from powershell:nanoserver-1809 and powershell:windowsservercore-1809 to mcr.microsoft.com/windows/nanoserver:ltsc2019 and mcr.microsoft.com/windows/servercore:ltsc2019 (both available) so we could get "proper" ltsc2019 images alongside the 1809 ones?

If Microsoft is not supporting an image for it, we probably shouldn't support it either, but I'm fine if someone wants to put in the work to get it working.

Sounds good to me

Someone who just has been bitten by this: https://community.jenkins.io/t/updating-powershell-7-version-included-with-jenkins-agent-docker-image/8691 (their Powershell version depends on the 1809 image as far as I can tell while they expect a version for LTS2019)
