Issue Description

I am experiencing a problem with the "powershell.codeFormatting.whitespaceBeforeOpenParen" setting.

Expected Behaviour

When formatting a PowerShell document, a space should separate the "param" keyboard and the following open paren "(".

Actual Behaviour

When I format a PowerShell document (press Ctrl + K; Ctrl + D), a space is not inserted bewteen the "param" keyboard and the open paren "(".

Commencez par le paramètre powershell.codeFormatting.whitespaceBeforeOpenParen et reproduisez le problème à l’aide de l’exemple joint Test-WhitespaceBeforeOpenParen.zip, en appliquant le formatage avec Ctrl + K; Ctrl + D. Comparez la sortie attendue et la sortie réelle, et utilisez la pièce jointe logs.zip si nécessaire. La tâche est terminée lorsque le formatage insère un espace entre le mot-clé param et la parenthèse ouvrante.
