[fix] pip install -e: legacy editable install (setup.py develop) is deprecated

From [1]: There is now a standardized mechanism [2] for an installer like pip to
request an editable install of a project.  pip is transitioning to using this
standard only instead of invoking the deprecated `setup.py develop` command.

For backward compatibility, we can use switches:

--use-pep517
  https://pip.pypa.io/en/stable/cli/pip_install/#cmdoption-use-pep517

--no-build-isolation
  https://pip.pypa.io/en/stable/cli/pip_install/#cmdoption-no-build-isolation

- [1] https://github.com/pypa/pip/issues/11457
- [2] https://peps.python.org/pep-0660/
