Disutils is deprecated in Python 3.12

[Zsailer]

See https://docs.python.org/3.10/whatsnew/3.10.html#distutils

nbclassic depends on distutils to build:

nbclassic/setup.py

Lines 72 to 97 in 9ae4cb1

	from distutils.command.build_py import build_py
	from distutils.command.sdist import sdist
	from setuptools.command.bdist_egg import bdist_egg
	from setuptools.command.develop import develop
	class bdist_egg_disabled(bdist_egg):
	"""Disabled version of bdist_egg
	Prevents setup.py install from performing setuptools' default easy_install,
	which it should never ever do.
	"""
	def run(self):
	sys.exit("Aborting implicit building of eggs. Use `pip install .` to install from source.")
	setup_args['cmdclass'] = {
	'build_py': css_js_prerelease(
	check_package_data_first(build_py)),
	'sdist' : css_js_prerelease(sdist, strict=True),
	'develop': css_js_prerelease(develop),
	'css' : CompileCSS,
	'backendtranslations': CompileBackendTranslation,
	'js' : CompileJS,
	'jsdeps' : Bower,
	'jsversion' : JavascriptVersion,
	'bdist_egg': bdist_egg if 'bdist_egg' in sys.argv else bdist_egg_disabled,
	}

This means, in Python 3.13 (released last week), using the setup.py to build nbclassic will fail.

Can we try:

• adding Python 3.13 to our test matrix,
• removing the distutils portion...and possibly replace the setup.py(?) for pyproject.toml?

Hi @RRosio, I would like to start to get involved in some Jupyter work, would this be a good one to take on?

[RRosio]

Hi @danyeaw thank you for your interest in taking this on! That would be great! I think this is an important issue for NBClassic, especially with pip 25.1 on the horizon.

I'd be happy to assist with anything you need, whether that is testing, review or if this ends up being a series of changes, I'd be happy to help out with those along the way!
