possible PLC2701 false positive

### Summary

Apolgies if I'm misunderstanding. But this:
```py
from mirror_syno.__main__ import main
```
is throwing PLC2701 on the last word 'main':
```
Private name import `__main__` from external module `mirror_syno`
```

There is no dunder in `main`. And I don't believe `__main__` as a module is a violation.
