Update set-up-windows-containers-with-powershell.md

[stackoverjoe]

Summary

The example Dockerfile did not work. Updated to get tag ltsc2019 which will be installed with powershell 7, so "RUN powershell.." switched to "RUN pwsh..".

Hi @stackoverjoe, thank you for submitting this PR.

If you use FROM mcr.microsoft.com/windows/servercore:ltsc2019 then by default it uses PowerShell version 5.

And that's the reason while running the step RUN pwsh -Command Add-WindowsFeature Web-Server fails with following error.

So it's better to keep the RUN powershell step as is.

FROM mcr.microsoft.com/windows/servercore:ltsc2019
LABEL Description="IIS" Vendor="Microsoft" Version="10"
RUN powershell -Command Add-WindowsFeature Web-Server
CMD [ "ping", "localhost", "-t" ]

And that can be run successfully.

Hi @sughosneo thank you for the reply.

I was mistaken by thinking that mcr.microsoft.com/powershell installed the same image on windows! Thank you for the correction!
