Switched broken pypip.in badges to shields.io

[raybellwaves]

• [NA] Closes #xxxx (remove if there is no corresponding issue, which should only be the case for minor changes)
• [NA] Tests added (for all bug fixes or enhancements)
• [NA] Tests passed (for all non-documentation changes)
• [NA] Fully documented, including whats-new.rst for all changes and api.rst for new API (remove if this change should not be visible to users, e.g., if it is an internal clean-up, or if this is part of a larger project that will be documented later)

This seems to be happening to a lot of projects as highlighted on the recent list of people who have cited this issue badges/shields#716.

Here is a project with a recent commit to resolve this which explains the issue better that I can pylint-dev/pylint-celery#7

This is a link to pypi (the Python package index), not pypip.in.

Thanks for looking into this, but I don't think this is actually relevant for us -- we already do not use pypip.in badges.
