[pyup-bot]

This PR updates setuptools from 46.1.3 to 46.2.0.

Changelog

46.2.0

-------

* 2040: Deprecated the ``bdist_wininst`` command. Binary packages should be built as wheels instead.
* 2062: Change 'Mac OS X' to 'macOS' in code.
* 2075: Stop recognizing files ending with ``.dist-info`` as distribution metadata.
* 2086: Deprecate 'use_2to3' functionality. Packagers are encouraged to use single-source solutions or build tool chains to manage conversions outside of setuptools.
* 1698: Added documentation for ``build_meta`` (a bare minimum, not completed).
* 2082: Filter ``lib2to3`` ``PendingDeprecationWarning`` and ``DeprecationWarning`` in testes,
because ``lib2to3`` is `deprecated in Python 3.9 <https://bugs.python.org/issue40360>`_.
