Remove pep8 workflow from ci

PEP-8 enforcements in the project are more of an annoyance than
anything. It doesn't really seem to add much value, and adds a lot of
friction to pull requests from developers who aren't familiar with the
style guide. Stylistic enforcements should just be done during PRs if
necessary (or a different style guide should be enforced).
