This would need to be an Adabot patch, but reviewing the CI, we're getting the following warnings:

• license = {text = "MIT"} => license = "MIT
• Similarly, license classifiers (License :: OSI Approved :: MIT License) is deprecated
• Some pre-commit hooks are throwing deprecation warnings, so it'd be good to update them (the problematic one is pre-commit/pre-commit-hooks)

@FoamyGuy this probably takes precedence over #511 and while they could be done together it's probably best not to, especially since this would be a straight git patch throughout the bundle. Happy to organize the patch to the libraries as well as the cookiecutter, any manual cleanup, etc. I could get started next week.
