[clang-format] missed space before operator when formatting expression inside requires

[chegoryu]

Clang format formats this code:

template<typename T, typename V>
concept CheckMultiplicableBy = requires(T a, V b) {
  { a * b } -> std::same_as<T>;
  { b * a } -> std::same_as<T>;
  { a *= b } -> std::same_as<T&>;
};

Into this:

template<typename T, typename V>
concept CheckMultiplicableBy = requires(T a, V b) {
  { a* b } -> std::same_as<T>;
  { b* a } -> std::same_as<T>;
  { a *= b } -> std::same_as<T&>;
};

I.e. removes space before *.

With brackets works fine:

template<typename T, typename V>
concept CheckMultiplicableBy = requires(T a, V b) {
  { (a * b) } -> std::same_as<T>;
  { (b * a) } -> std::same_as<T>;
  { a *= b } -> std::same_as<T&>;
};
