primer.json is not installed

[hroncok]

Describe the bug The black-primer tool uses primer.json on runtime, but the file is not installed.

To Reproduce Steps to reproduce the behavior:

[tmp]$ python -m venv venv
[tmp]$ . venv/bin/activate
(venv) [tmp]$ pip install black
...
Installing collected packages: toml, click, appdirs, mypy-extensions, pathspec, regex, black
Successfully installed appdirs-1.4.4 black-21.4b1 click-7.1.2 mypy-extensions-0.4.3 pathspec-0.8.1 regex-2021.4.4 toml-0.10.2
(venv) [tmp]$ which black-primer
~/tmp/venv/bin/black-primer
(venv) [tmp]$ black-primer
Usage: black-primer [OPTIONS]
Try 'black-primer -h' for help.

Error: Invalid value for '-c' / '--config': Path '/home/churchyard/tmp/venv/lib64/python3.9/site-packages/black_primer/primer.json' does not exist.

Expected behavior site-packages/black_primer/primer.json should be installed

Environment (please complete the following information):

• Version: at least 20.8b1 to 21.4b1 but possible any
• OS and Python version: Fedora Linux / Python 3.9.4 (but also happens on any other version)

Does this bug also happen on master? Yes

Working on a fix

A simple package_data mod should fix it:

black/setup.py

Line 67 in 1728bb4

package_data={"blib2to3": ["*.txt"], "black": ["py.typed"]},

Thanks for noticing!

[hroncok]

Yes, I have that ready, now going trough https://github.com/psf/black/blob/master/CONTRIBUTING.md

[hroncok]

Ready in #2154

This is interesting. I didn't package the config, as I would expect anyone running it locally to want to run their own configs on their own projects. E.g. $ORG has 10 black repos, before bringing in a new version or as a check primer could check to see if everything is black compliant.

I can see the benefit of including this default config tho. So will accept the PR. Thanks!
