[dependabot-preview]

Bumps setuptools from 49.6.0 to 50.0.3.

Changelog

Sourced from setuptools's changelog.

v50.0.3

• #2363: Restore link_libpython support on Python 3.7 and earlier (see 50.0.0 can't build extensions for Python < 3.8 if Py_ENABLE_SHARED pypa/distutils#9).

v50.0.2

• #2352: In distutils hack, use absolute import rather than relative to avoid bpo-30876.

v50.0.1

• #2357: Restored Python 3.5 support in distutils.util for missing subprocess._optim_args_from_interpreter_flags.
• #2358: Restored AIX support on Python 3.8 and earlier.
• #2361: Add Python 3.10 support to _distutils_hack. Get the 'Loader' abstract class from importlib.abc rather than importlib.util.abc (alias removed in Python 3.10).

v50.0.0

• #2232: Once again, Setuptools overrides the stdlib distutils on import. For environments or invocations where this behavior is undesirable, users are provided with a temporary escape hatch. If the environment variable SETUPTOOLS_USE_DISTUTILS is set to stdlib, Setuptools will fall back to the legacy behavior. Use of this escape hatch is discouraged, but it is provided to ease the transition while proper fixes for edge cases can be addressed.
• #2334: In MSVC module, refine text in error message.
