Rearranging the language list with PowerShell

The region/language section of the Settings app allows reordering the language preferences by using the up and down arrows that appear when a language entry is selected. The order can also be changed with PowerShell. The Get-WinUserLanguageList cmdlet retrieves a list. The items can be swapped just like in any other collection, then the revised list can be made the new order with Set-WinUserLanguageList.
