default settings for PSScriptAnalyzer are different to the CLI

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

the default PSScriptAnalyzer config in the vscode extension seems to be different to the default config in the CLI

> Invoke-ScriptAnalyzer .\windows\foo.ps1

RuleName                            Severity     ScriptName Line  Message
--------                            --------     ---------- ----  -------

                                                                  because it might not work in all hosts, does not work when  
                                                                  there is no host, and (prior to PS 5.0) cannot be
                                                                  suppressed, captured, or redirected. Instead, use
                                                                  Write-Output, Write-Verbose, or Write-Information.

creating a PSScriptAnalyzerSettings.psd1 file and enabling the rule explicitly seems to fix it:

@{
    Severity=@('Error','Warning')
    IncludeRules=@('PSAvoidUsingWriteHost')
}

but i would rather not have to configure every single rule in order to have consistent behavior in the CLI and vscode

Steps to Reproduce

1. install PSScriptAnalyzer: Install-Module -Name PSScriptAnalyzer -Force -scope currentuser
2. create foo.ps1 with the following content:

   write-host asdf
   

3. run Invoke-ScriptAnalyzer .\foo.ps1 and observe that the error is reported only in the CLI but not in vscode

No response

まず、拡張機能による PSScriptAnalyzer の呼び出しを追跡し、そのデフォルト値を、報告された Invoke-ScriptAnalyzer .\foo.ps1 の結果と比較します。write-host asdf を含む foo.ps1 で再現します。PSScriptAnalyzerSettings.psd1 ファイルなしで同じデフォルト診断が VS Code に表示されれば完了です。
