Missing / Incorrect Definition

The Intl.Collator object has a compare method which is declared as compare(x: string, y: string): number; but according to the relevant spec is actually get compare(): (this: void, x: string, y: string) => number. Importantly, the spec states that

The returned function is bound to collator so that it can be passed directly to Array.prototype.sort or other functions

Sample Code

I'm having trouble putting together a Playground example that cares about the difference (which is admittedly subtle!) but it's the cause of https://github.com/typescript-eslint/typescript-eslint/issues/7098
