py-setuptools: update to 68.1.2.

v68.1.2
=======

Misc
----

- #4022, #4022

v68.1.1
=======

Bugfixes
--------

- Fix editable install finder handling of nested packages, by only handling 1
  level of nesting and relying on ``importlib.machinery`` to find the remaining
  modules based on the parent package path. (#4020)

v68.1.0
=======

Features
--------

- Removed code referencing bdist_wininst in install_scripts. (#3525)
- Promote ``pyproject.toml``'s ``[tool.setuptools]`` out of beta.
  Note that some fields are still considered deprecated and/or obsolete,
  and these might be removed in future versions (i.e., there is no guarantee
  for long term support and backward compatibility on those fields). (#3962)
- Automatically add files listed in ``Extension.depends`` to sdists,
  as long as they are contained in the project directory -- by :user:`RuRo` (#4000)
- Require Python 3.8 or later.

Bugfixes
--------

- Made imports in editable installs case-sensitive on case-insensitive filesystems -- by :user:`aganders3` (#3995)
- Use default encoding to create ``.pth`` files with ``editable_wheel``. (#4009)
- Detects (and complain about) ``scripts`` and ``gui-scripts`` set via ``setup.py``
  when ``pyproject.toml`` does not include them in ``dynamic``. (#4012)

Misc

- #3833, #3960, #4001, #4007
