TypeScript: Keep trailing comma in tsx type parameters ([#6115] by [@sosukesuzuki])

Previously, a trailing comma after single type parameter in arrow function was cleaned up. The formatted result is valid as ts, but is invalid as tsx. Prettier master fixes this issue.

// Input
type G<T> = any;
const myFunc = <T,>(arg1: G<T>) => false;

// Output (Prettier stable)
type G<T> = any;
const myFunc = <T>(arg1: G<T>) => false;

// Output (prettier master)
type G<T> = any;
const myFunc = <T,>(arg1: G<T>) => false;
