feat(python): encode positional-only arguments in signatures
Now that Python 3.7 reached end-of-life, and since Python 3.8 and greater have support for positional-only argument notation (any argument before a / delimiter may only be passed positionally), adjust code generation to leverage this feature in order to address issues where inheritance hierarchies would rename parameters, which is a non-issue in all languages but Python, where those could always be provided as keyword arguments before.
Fixes https://github.com/aws/jsii/issues/4541
BREAKING CHANGE: the generated Python code now requires Python 3.8 or later and encodes positional arguments as positional-only, making keyword-style usage impossible. Users who used the keyword-style convention need to update their code to use the positional syntax instead.

where inheritance hierarchies would rename parameters
Is it necessary to rename them? I think it would be much better to keep keyword-style parameters and just use the parameter names consistently. For me it is a great benefit of Python and in many cases it would be even better to have keyword-style-only parameters other than positional-only.
