Bump setuptools from 44.1.1 to 49.6.0 in /docker/build_scripts

[dependabot-preview]

Bumps setuptools from 44.1.1 to 49.6.0.

Changelog

Sourced from setuptools's changelog.

v49.6.0

• #2129: In pkg_resources, no longer detect any pathname ending in .egg as a Python egg. Now the path must be an unpacked egg or a zip file.

v49.5.0

• #2306: When running as a PEP 517 backend, setuptools does not try to install setup_requires itself. They are reported as build requirements for the frontend to install.

v49.4.0

• #2310: Updated vendored packaging version to 20.4.

v49.3.2

• #2300: Improve the safe_version function documentation
• #2297: Once again, in stubs prefer exec_module to the deprecated load_module.

v49.3.1

• #2316: Removed warning when distutils is imported before setuptools when distutils replacement is not enabled.

v49.3.0

• #2259: Setuptools now provides a .pth file (except for editable installs of setuptools) to the target environment to ensure that when enabled, the setuptools-provided distutils is preferred before setuptools has been imported (and even if setuptools is never imported). Honors the SETUPTOOLS_USE_DISTUTILS environment variable.

v49.2.1

• #2257: Fixed two flaws in distutils._msvccompiler.MSVCCompiler.spawn.

v49.2.0

• #2230: Now warn the user when setuptools is imported after distutils modules have been loaded (exempting PyPy for 3.6), directing the users of packages to import setuptools first.

v49.1.3

• #2212: (Distutils) Allow spawn to accept environment. Avoid monkey-patching global state.
• #2249: Fix extension loading technique in stubs.

v49.1.2
