Fix style (#1378)

* style: change to double quotes

fix: switch from `python-version` to `target-version` and set to minimum
Python 3.8

* fix: escape regex backslash

* style: black enforces single newline before imports

* style: fix up tests

* fix: add missing star for keyword arguments unpacking
