QuickGELU: the sigmoid GELU approximation.

$$
\mathrm{quick\_gelu}(x) = x\,\sigma(1.702\,x)
$$

**Throws**

- `ClikaRT::Error`: when the input's dtype is not served for this operation (the machine-readable reason rides `code_name()`).

**Returns:** a new tensor, same shape and dtype as `input`.

```cpp
auto y = ClikaRT::ops::quick_gelu(x);
```
