Steps to reproduce

Since #18116 has been implemented, I have tried to use it when filling out issues on my remote setup, but I need to pipe it via Out-String for it to work properly. This seems to be caused by it not implementing ToString() correctly, instead relying on formatters to display its information.

Expected behavior

> $PSVersionTable | Set-Clipboard
> Get-Clipboard # Ctrl+Shift+V

首先使用 $PSVersionTable、Set-Clipboard 和 Get-Clipboard 重现报告中的管道，然后跟踪 PSVersionHashTable 类型及其字符串转换行为。当直接将 $PSVersionTable 通过管道传递给 Set-Clipboard 时，无需 Out-String 即可生成 Expected behavior 下所示的格式化名称和值输出，即表示完成。
