Updated linting tooling (#2350)

Removed the pins to some of our linting tools to make sure we have the newest tools. (But pinning `flake8` because later versions dropped Python 2 support)

Also fixed some problems the new tools showed.

Also made sure that dependabot does not bug us about `flake8` and `jsonschema` anymore.
