Additional settings file for developement

Summary of the new feature

There is currently one PSScriptAnalyzerSettings.psd1 file shipped with the PSScriptAnalyzer but there are at least two use cases with a different requirement:

• Design-time
  During this phase (often done is VSCode or Visual Studio), any cutting-edge alert for a potential PowerShell pitfall is welcome.

• Continuous Integration
  During this phase (e.g. in a CI/CD street), any change is supposed to passed the given tests.

Apparently, there is a (undocumented?) convention that our convention is to ship it opt-in via ConfigurableRule with Enable = false but that convention only satisfies the builder phase.

Proposed technical implementation details (optional)

Ship the PSScriptAnalyzer with an additional settings file that is focused on the development phase.
The "development" settings file might than be used as a default by e.g. VSCode (powershell.scriptAnalysis.settingsPath).

Caveats

• The settings file under VSCode "This setting may not work as expected currently!", see: https://github.com/PowerShell/vscode-powershell/issues/4653
• https://github.com/PowerShell/vscode-powershell/issues/5385? "Users keep getting bitten by the extension's effective defaults differing from Invoke-ScriptAnalyzer's defaults", I believe this isn't a feature but a bug, see: https://github.com/PowerShell/vscode-powershell/issues/5474

What is the latest version of PSScriptAnalyzer at the point of writing

1.25.0

同梱されている PSScriptAnalyzerSettings.psd1 と、issue で言及されている VSCode の powershell.scriptAnalysis.settingsPath 設定から始めます。設計時と CI の要件を比較し、そのうえで開発に重点を置いたルールと、追加ファイルをどのように同梱すべきかを決定します。既存の設定ファイルを変更せずに、開発用の個別の設定ファイルを利用できる状態を完了とします。
