Upgrade black (&& other dependencies)

[JKatzwinkel]

Apparently, there's an issue in typed-ast which causes the version of black to which our dependencies are locked (20.8b1) to crash when running on python 3.9.8 (!!????):

• https://stackoverflow.com/a/69913764/1933494
• Module load fails with Python 3.9.8 (undefined symbol _PyUnicode_DecodeUnicodeEscape) python/typed_ast#169 (comment)

Tbh I don't quite get what exactly is going on but it seems we have 2 options:

1. either wait for a types-ast release containing the fix in Define _PyUnicode_DecodeUnicodeEscape even on Python 3.6+ python/typed_ast#171
2. or upgrade to black^=21.10b0 (which doesn't use typed-ast apparently), which in turn requires python^=3.6.2 and also there are other errors all of a sudden, so I ended up just upgrading everything.

I hereby propose the second option.

had you tried to just to poetry update? i'd like to not pin black to a version during its beta phase.

did this also occur locally for you? in this case i'd rather propose a CONTRIBUTING.md and get that right.

Just doing a poetry update doesn't cut it: https://github.com/JKatzwinkel/delb/runs/4181523684?check_suite_focus=true

When I first encountered the problem yesterday, it was only in the Github actions CI pipeline logs. Locally, under Python 3.9.7, I had no issues. However, after switching to Python 3.9.8, I can indeed replicate this locally:

i'd like to post the catatonic emoji with the empty eyes.

i'll ignore the problem for a while so it may disappear as it came up.

the next poetry release will offer a dependencies group feature that i need and want to use to put doc related libs into to fix the unit test workflow on GH actions. let's hope the release will not break other things. maybe that feature will help here to.

ok let's sleep on it

@JKatzwinkel please check your local results, mine and the CI's are fine.
