py-atpublic: updated to 4.0

4.0 (2023-06-05)
Drop Python 3.7 support
Remove public.install() which was used to inject the public and private \ 
functions into the builtins namespace. This isn’t very helpful and could be \ 
actively harmful. Explicit is better than implicit.
The functional form of public() now returns the argument values in the order \ 
they are given. This allows you to explicitly bind those values to names in the \ 
global namespace. While this is redundant, it does solve some linter problems.
Switch from flake8 and isort to ruff for code quality.
Bump dependencies.
