YT: Add type name of std::exception to error text in TError constructor

Без этого, исключение о выходе за пределы массива в векторе выглядит так:

```
vector
    origin           (pid 178121, thread library-cpp-yt-)
    datetime        2025-03-31T14:59:49.069209Z
```

С фиксом:
```
vector
    origin           (pid 178121, thread library-cpp-yt-)
    datetime        2025-03-31T14:59:49.069209Z
    exception_type  std::out_of_range
```
