Allow setting line length, when setting `black` as autoformatter

Problem Description

When setting black as autoformatter, the line-length (and the vertical ruler) are set and fixed to 88. Related: #14082

What steps reproduce the problem?

1. set Preferences -> Completion and linting -> Code formatting -> Choose the code formatting provider to black
2. Preferences -> Completion and linting -> Code style -> Maximum allowed line length is auto. set to 88
3. can’t change this Maximum allowed line length

What is the expected output? What do you see instead?

Preset of 88 for black is fine, but since black provides the -l option (link), the maximum line length should be changeable.

Hey @ccaprani, we’re aware this problem resurfaced again (see issue #14558). We’ll try to fix it in our next version (5.2.0), to be released at the end of September.
