'Implement interface' quick fix generates bodies in ambient contexts

[DanielRosenwasser]

interface Hook {
    tap(): void
}

declare class SyncHook implements Hook {
    
}

Try using the "Implement interface" quick fix on SyncHook.

Expected:

declare class SyncHook implements Hook {
    tap(): void;
}

Actual:

declare class SyncHook implements Hook {
    tap(): void {
        throw new Error("Method not implemented.");
    }

}
