Fix passing a dict for builder.

Do to a unintended operator precedence, ruff
later added brackets where they do not belong.
This moves them and fixes the bug where
passing a dictionary to the `builder` keyword
of `DefaultDriver` wasn't possible.
Fixes #27.

* sphinx_polyversion/driver.py (DefaultDriver): Fix.
