Support variable substitution to refer to workspaceFolder / rootDir in eslint.options setting

[rdsedmundo]

I'd like to configure the eslint.options setting to use my .gitignore at the root of my monorepo, unfortunately, there's no way to refer to the root directory, and because I'm making use of eslint.workspaceDirectories, I get errors depending on the nesting of my packages (not everything is under packages/* just), saying that the file could not be found.

Something like this:

  "eslint.options": {
    "ignorePath": "${workspaceFolder}/.gitignore"
  }

This is best supported in VS Code itself and dups microsoft/vscode#2809

I just faced this again on a repo where I have a single package that is not in a workspace and I'm referencing the ignorePath as ../../.gitignore.

The VSCode issue that you linked is more than 5 years old. Couldn't you reconsider opening this again? I'd be open to contributing, we can always remove our implementation here if VSCode makes it built-in in the future.

I think it makes more sense then to contribute this to VS Code itself then having a custom implementation here in ESLint.
