PSAvoidOverwritingBuiltInCmdlets (core-6.1.0-*) returns warning for Write-Log, which is not a built-in cmdlet

Comece pelos arquivos de configurações de plataforma do core-6.1.0 em Engine/Settings, especialmente pelas entradas próximas a Write-Log, e compare as listas de cmdlets integrados no Linux ARM, Linux, macOS e Windows. Remova ou corrija as entradas que não são distribuídas com o PowerShell e, em seguida, execute Invoke-ScriptAnalyzer na reprodução de Write-Log.psm1 e verifique se há avisos falsos semelhantes.

Before submitting a bug report:

• Make sure you are able to repro it on the latest released version
• Perform a quick search for existing issues to check if this bug has already been reported

Steps to reproduce

Create a file called Write-Log.psm1 in your home directory and populate it with an empty function called Write-Log:

function Write-Log {
}

Install and run PSScriptAnalyzer against the file:

> Install-Module PSScriptAnalyzer

> Invoke-ScriptAnalyzer -Path ~\Write-Log.psm1

Expected behavior

PSScriptAnalyzer returns no findings because Write-Log is not a built-in cmdlet.

Actual behavior

RuleName                         Severity ScriptName     Line Message
--------                         -------- ----------     ---- -------
PSAvoidOverwritingBuiltInCmdlets Warning  Write-Log.psm1 1    'Write-Log' is a cmdlet that is included with PowerShell (version core-6.1.0-windows) whose definition should not be overridden

This behaviour should be reproducible cross-platform.

Troubleshooting

Write-Log was never shipped with any version of PowerShell, but it is erroneously defined as a built-in cmdlet:

https://github.com/PowerShell/PSScriptAnalyzer/blob/e2804796f43eab60f5d105f6bbaea83fb446a13d/Engine/Settings/core-6.1.0-macos.json#L1391-L1395

https://github.com/PowerShell/PSScriptAnalyzer/blob/e2804796f43eab60f5d105f6bbaea83fb446a13d/Engine/Settings/core-6.1.0-windows.json#L1692-L1696

Probable cause is described in https://github.com/PowerShell/PowerShell/issues/7209 as an upstream issue in PSDesiredStateConfiguration that was reportedly fixed in 2020. However, the PSScriptAnalyzer files affected by that issue were never rebuilt afterwards.

The module that may have caused this problem at the time is https://github.com/microsoft/PowerShellForGitHub, which defines Write-Log and then suppresses PSScriptAnalyzer reports in Helper.ps1#L128. The PR to suppress that finding is recorded in https://github.com/microsoft/PowerShellForGitHub/pull/180. If this module was present in the build environment, then PSScriptAnalyzer would have added Write-Log and possibly other cmdlets to the list of built-in cmdlets even though they do not ship with PowerShell.

As a result, default installations of PSScriptAnalyzer return a false warning for PSAvoidOverwritingBuiltInCmdlets against cmdlets named Write-Log.

It is possible that there may be other cmdlets erroneously included in these files for the same reason.
