languageServerHaskell.useCustomHieWrapperPath option don't work properly with workspaceFolder variable on Windows

[QuietJoon]

When I set languageServerHaskell.useCustomHieWrapperPath with absolute path or ${HOME} variable, it works.
However, with ${workspaceFolder}, it doesn't parse the path properly when running VSCode on Windows but parses the path as *unix way

Works well:

• "languageServerHaskell.useCustomHieWrapperPath": "${HOME}/hie.bat"
• "languageServerHaskell.useCustomHieWrapperPath": "${HOME}\hie.bat"
• "languageServerHaskell.useCustomHieWrapperPath": "A:\ABSOLUTEPATH\hie.bat"

Not works:

• "languageServerHaskell.useCustomHieWrapperPath": "${workspaceFolder}/hie.bat"
  • Error message: Launching server using command /t:/WORKSPACEFOLDER/hie.bat failed.
• "languageServerHaskell.useCustomHieWrapperPath": "${workspaceFolder}\hie.bat"
  • Error message: Launching server using command /t:/WORKSPACEFOLDER\hie.bat failed.
