  "folders": [
     {
       "name": "root",
       "path": ".",
      },
    ]
...
  "go.formatTool": "custom",
   "go.alternateTools": {
     "customFormatter": "${workspaceFolder:root}/bin/golangci-lint",
    },

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:

1. Create a vscode workspace
2. Set the workspace settings from above
3. Save a golang file to trigger the formatter

I think this is a duplicate of #2582. Seems to be fixed in nightly extension
