Add pyproject.toml instead of setup.py

Add a question to generate pyproject.toml files instead of setup.py.

thought: Couldn't we just add this always? IIUC, having a pyproject.toml file based on whool inside the addon dir, and having a setup/ folder based on setuptools-odoo, shouldn't conflict, right? Whool would just be the new official way to install addons, and setuptools-odoo would be deprecated and exist only on older branches.

I wouldn't do both simultaneously in any case, even if they don't conflict. A single source of truth is more important, and it's far easier to debug problems if you don't also have to divine which package installation method is being used.

But I've not properly reviewed the code, so I may change my mind.

Yes I chose to have one OR the other because they are sometimes modified manually and we don't want to tell people to modify both in that case.
