Don't ship CHANGELOG with wheels

[akx]

Describe the bug

Upon uninstalling the package (temporarily, don't worry! 😁 ), I noticed it had dropped a CHANGELOG.md in site-packages. It probably shouldn't.

$ pip uninstall flake8-annotations
Found existing installation: flake8-annotations 2.6.2
Uninstalling flake8-annotations-2.6.2:
  Would remove:
    .../lib/python3.9/site-packages/CHANGELOG.md
    .../lib/python3.9/site-packages/flake8_annotations-2.6.2.dist-info/*
    .../lib/python3.9/site-packages/flake8_annotations/*

To Reproduce

Minimal code example to reproduce the behavior:

• install flake8-annotations
• look in your site-packages

Version Information

• flake8-annotations 2.6.2
• Python 3.9
• pip 20.3.1

Interesting! Never noticed this. I guess I've never uninstalled 😄

I think this was just copied from Poetry's documentation when this was moved from pipenv. I'll change it now so future releases won't do this.

Thanks!
