isort: remove settings covered by profile (#3281)

* chore: remove isort settings covered by profile

https://black.readthedocs.io/en/stable/guides/using_black_with_other_tools.html#custom-configuration

* chore: add myself to CONTRIBUTORS file

* chore: use black profile for isort

* chore(isort): fix configuration to skip directories

When overwriting `skip`, `.git` and others would no longer be skipped.

`extend_skip` is the correct option.

* chore(isort): skip directory `qt/bundle`
