Normalize `operator()` spelling in YT

As of the date of this PR, there are 4 different ways to spell parenthesis operator in YT

* `operator()(args...)` - 505 occasions
* `operator() (args...)` - 151 occasions
* `operator () (args...)` - 65 occasions
* `operator ()(args...)` - 6 occasions

As is apparent from this statistics, the first way is the most popular by far (69% of all matches). Furthermore, it is the most consistent with YT style guide <https://nda.ya.ru/t/YOfm_T4z7Syke2>.
