Possible mis-documentation example

[kieran-osgood]

Hey - was just checking out this lib and wondered, in this example:

### Testing definitions

expectType<number>(add(1, 2));
expectType<TypeEqual<boolean, ReturnType<typeof add>>>(true);
expectType<TypeEqual<[number, number], Parameters<typeof add>>>(true);

Should the middle line actually read:

expectType<TypeEqual<number, ReturnType<typeof add>>>(true);
//                   ^ changing this to a number

As add returns a number not a boolean?

Your fix looks correct to me, did you want to open a PR?

Will do just that when I'm home!
