`boolean-positional-value-in-call` (`FBT003`) - don't warn when function name starts with `set_` and only takes one argument

functions like these should not report the error imo, since the meaning of the bool is self explanatory, which is often the case when the functin starts with `set_`:

```py
def set_enabled(enabled: bool):
    ...

set_enabled(True) # self explanatory
set_enabled(enabled=True) # unnecessary/redundant
```
