Describe the bug

I'm in a multi root workspace with many go packages
I'm trying to point my custom formatter at ./bin/golangci-lint. This is located within the workspace root
The formatter fails with ${workspaceFolder:root}/bin/golangci-lint is not found.
If i remove the scoping: "customFormatter": "${workspaceFolder}/bin/golangci-lint", then the formatter fails with <path-to-current-folder>/bin/golangci-lint is not found.. The substitution works as expected but this changes for files in each workspace folder so its not really a usable config

Steps to reproduce the behavior:

Create a vscode workspace
Set the workspace settings from above
Save a golang file to trigger the formatter

golang / vscode-go
