Have PowerShell formatter remove trailing whitespace when formatting a file

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.

Summary

When allowing the PSScriptAnalyzerSettings.psd1 to show Information-level problems, it adds a lot of overhead in formatting files that have lines with trailing whitespaces. Since this recommendation is mostly aesthetic/non-breaking, as is the automated code formatting in general, I'd like to see the formatter for PowerShell remove these trailing whitespaces characters.

Because we can't store a centralized configuration for PSScriptAnalyzerSettings.psd1 in source control at the repo/workspace level to have it be taken automatically be any user working on that repo, having per-user rules to suppress this aren't really practical. I did see a separate thread in this project's issues noting individual users can set a configuration flag to do this, but again, having every user do that themselves vs. having a central linting rule is frustrating to maintain adherence on. Short of having a CI/CD pipeline hard reject any PSScriptAnalyzer errors to force them to check in cleaned code, an automated approach is best.

Proposed Design

No response

Das Issue nennt keine Quelldatei und keinen Test. Beginne damit, die Implementierung des PowerShell-Formatierers in dieser TypeScript-VS Code-Erweiterung zu finden, und reproduziere die Formatierung anhand einer Datei mit nachgestellten Leerzeichen. Erledigt ist die Aufgabe, wenn die formatierte Ausgabe nachgestellte Leerzeichen entfernt, ohne nicht relevante Inhalte zu ändern, und dies durch die relevanten Formatierungstests abgedeckt ist, sofern solche vorhanden sind.
