Disabled GH Windows Runner until the agent uses a new version of pwsh

[Manbearpiet]

We cannot build at the moment using windows because of a dependency on at least PowerShell 7.3.

At C:\Users\runneradmin\Documents\PowerShell\Modules\PowerShellBuild\0.6.1\Public\Build-PSBuildMarkdown.ps1:35 char:19 + … oduleInfo = Import-Module "$ModulePath/$ModuleName.psd1" -Global -For … +               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

[<<==>>] Exception: The version of PowerShell on this computer is '7.2.16'. The module 'D:\a\AzureDevOpsPowerShellAPI\AzureDevOpsPowerShellAPI\Output\AzureDevOpsPowerShell\AzureDevOpsPowerShell.psd1' requires a minimum PowerShell version of '7.3' to run. 
Verify that you have the minimum required version of PowerShell installed, and then try again.

Issue is tracked at actions/runner-images#8847 once this issue is fixed, we can further release again with builds on Windows GH hosted runners.
