What issue does this fix?

Typescript allow annotating this parameter https://www.typescriptlang.org/docs/handbook/functions.html#this-parameters

function f(this: void) {
  // make sure `this` is unusable in this standalone function
}

Because this parameters are fake parameters, I think we should skip these.

Thanks. Can you also create a normal issue to track this problem. This helps us track issues and verify this PR fixed it

I had created #104877 to track this issue. Thanks.

Thanks! This will be in the next VS Code insiders build and is scheduled to ship with VS Code 1.49
