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 "(".

从 powershell.codeFormatting.whitespaceBeforeOpenParen 设置开始，使用附加的 Test-WhitespaceBeforeOpenParen.zip 示例，通过 Ctrl + K; Ctrl + D 进行格式化来重现该问题。比较预期输出和实际输出，并在需要时使用 logs.zip 附件。完成的标准是格式化会在 param 关键字和左括号之间插入一个空格。
