PycodestyleBear: Require pycodestyle 2.2

[jayvdb]

PycodestyleBear was added (9004380) without an explicit
entry in requirements.txt, so it inherited the requirement
pycodestyle>=2.2 from autopep8.

Thanks for your contribution!

Reviewing pull requests take really a lot of time and we're all volunteers. Please make sure you go through the following check list and complete them all before pinging someone for a review.

• I have rebased properly. Please see this for a tutorial.
• I have gone through the commit guidelines and I've followed them:
• I have followed the guidelines for the commit shortlog.
• I have followed the guidelines for the commit body.
• I have included the issue URL.
• I have used the Fixes keyword if the commit fixes a real bug and the Closes keyword if it adds a feature/enhancement. See more here.
• I have run all the tests and they all pass. That includes that all CI (below) is green - if GitMate issues appear you will have to amend your commits, pushing new commits on top is not sufficient!

As you learn things over your Pull Request please help others on the chat and on PRs to get their stuff right as well!
