Use pre-commit for 'pep8' tox target, bump versions

We want to bump the versions of hacking, but doing so requires changes
in two places: '.pre-commit-config.yaml' and 'tox.ini'. This is silly:
we can simply use tox to handle pre-commit and leave all other
dependencies to pre-commit. Do this, migrating bandit to pre-commit and
bumping the other dependencies in the process.

We remove the 'fast8' target and tool, since pre-commit is plenty fast
here.
